Killshot 2 Pro EFI System
The Killshot 2 Pro is the ultimate evolution of our throttle body EFI lineup—built on the proven foundation of Killshot 2 and enhanced with deeper tuning control, dual-quad capability, and upgraded hardware. It includes every feature of Killshot 2 plus expanded tables and strategies for serious builders who want maximum flexibility and precision. Over the past two years, we’ve gathered real-world feedback from tuners, racers, and street enthusiasts to refine and improve every aspect of the system. The result is an EFI package that’s more powerful, more versatile, and even easier to install and tune.
Why upgrade from a carburetor?
Carburetors demand constant compromise. EFI doesn’t. Killshot 2 Pro dynamically adjusts fuel delivery in real time for weather, altitude, and load—eliminating hesitation, cold-start issues, and the need to re-jet for changing conditions. Expect precision fuel control, improved throttle response, and seamless adaptability whether you’re cruising in traffic, blasting down the strip, or hunting laps at the track.
Engineered for power and durability
At the core is a high-speed 32-bit ECU delivering fast, accurate engine management for naturally aspirated and boosted combos. An integrated 3-bar TMAP sensor supports up to 27 psi of boost for turbo and supercharged applications. Each throttle body carries four 100 lb/hr injectors, comfortably supporting up to 650 HP per unit. Need more? Run dual-quad and fuel up to 1,200 HP (requires an additional slave unit; second unit sold separately).
Maintaining proper fuel pressure is critical for EFI performance. The Pro’s built-in fuel pressure sensor gives you real-time fuel pressure monitoring, ensuring consistent delivery under all conditions—no external sensors or guessing.
Remote-mounted ECU for reliability
Many EFI systems bury the ECU inside the throttle body, where heat and vibration shorten lifespan. Killshot 2 Pro uses a separate, remote-mounted ECU to keep electronics cool, stable, and serviceable for the long haul.
Expanded tuning & control
Killshot 2 Pro takes tuning further while keeping day-to-day operation simple:
- 31×31 VE Fuel Tables – Higher resolution across the full load/RPM range.
- 31×31 MBT Spark Tables – More precise ignition control under any condition.
- Closed-Loop Learning (expanded resolution) – Smarter corrections for street and mild builds.
- Self-Learning Strategy (clarified): The system does not “self-tune” end-to-end. You select a base calibration matched to your combo; the ECU refines fueling as you drive. Ideal for stock-to-mild engines. Aggressive setups—high-lift cams, forced induction, or nitrous—benefit from manual tuning for optimal results.
- Progressive Throttle Linkage – Smoother, more linear tip-in for excellent street manners versus “on/off” TBI behavior.
- Boost Control & Fuel Level Inputs – Hardware-ready for future software unlocks (e.g., boost-solenoid control, dash integration).
Handheld + PC software
Every Pro system includes our 3rd-generation 5" HD touchscreen handheld for setup, data viewing, and real-time diagnostics. For advanced users, the Pro PC Tuning Suite provides manual access to AFR targets, ignition strategies, boost enrichment, and more.
Built for easy installation & maximum compatibility
EFI conversions shouldn’t be complicated. Killshot 2 Pro is designed for straightforward installs and broad compatibility:
- Fits 4150-flange 4-barrel intake manifolds (universal 4-barrel fitment)
- Low-profile throttle body design works with more air cleaner setups—including drop-base filters
- Standalone or Complete Kit options to match your build plan
Who it’s for
Whether you’re refining a weekend cruiser, dialing in a high-compression race motor, or pushing a turbocharged street car, Killshot 2 Pro delivers the reliability and power of modern EFI with the simplicity of a 4-barrel TBI—plus headroom to grow.
System features (all the benefits of Killshot 2, plus more)
- Supports up to 650 HP per unit (NA) / up to 1,200 HP in dual-quad (NA)
- Four 100 lb/hr fuel injectors per throttle body
- Integrated 3-bar TMAP sensor – Supports up to 27 psi boost
- Built-in fuel pressure sensor – Real-time fuel pressure monitoring for precise control
- Progressive throttle linkage – Smooth response and drivability
- Remote-mounted ECU – Improved reliability and serviceability
- TPS output – For transmission controllers, nitrous activation, and other external modules
- 4150 flange – Universal fitment for 4-barrel intake manifolds
- Low-profile design – Compatible with more air cleaner options, including drop-base filters
- Available finishes: Black, Polished, Gold
- Standalone or Complete Kit Options – Choose the package that fits your build
What you can expect
- Faster starts in all weather, stable idle quality, and crisp throttle response
- Consistent fueling on the street, track, or strip—even with altitude and temperature swings
- Easy initial setup with room to grow into advanced tuning as your combo evolves
Killshot 2 Pro gives you everything enthusiasts love about Killshot 2—and then some. If you’re upgrading from a carburetor or stepping up from a basic EFI, the Pro is the intelligent path to fuel, tune, and dominate with confidence.

Most common questions
Quick answers to our most common queries for this product.
The Killshot 2 Pro EFI System is designed to work with any classic 4, 6, or 8 cylinder engine that is under 650 hp, uses a 4150 style flange, and has a fuel system rated for EFI (43 PSI).
The self learn will work for most stock-mild builds, while some mild and more advanced builds may require manual tuning.
The Killshot 2 Pro EFI System is designed to work with most stock or aftermarket ignition components. It will work with most tachometers and is compatible with Dakota Digital dashes using their Aces BIM Module (BIM-EFI-1).
Self-tuning is a common term used among aftermarket EFI companies, but we prefer the term "self-learning" as that is more accurate, even for our competitors who advertise "self-tuning."
Our systems are designed to self-learn the fuel MAPs and work best for stock-mild builds. Some mild builds and anything beyond that would require manual tuning, of which the system is fully capable. Additional features like nitrous and boost are also considered beyond stock and require manual adjustments to enable and configure these kinds of features.
Yes! You can make many changes using the Bluetooth or handheld interface, and we also offer a free PC app for more advanced tuning.
The Killshot 2 Pro EFI System can work with standard stock or aftermarket ignition components, but if you want to run timing control, it will need either a magnetic pickup distributor that has been locked out or a Hall Effect distributor. You will also need to make sure that your fuel delivery system can support 43-58 PSI. Whether or not you need a return line will depend on your fuel delivery system and if the regulator is inside or outside the tank. Whether or not you need to replace your tank will depend on which fuel delivery system you choose. We offer complete Master Kits for each EFI system that come with new ignition components and a fuel delivery system. You can visit the Killshot Fusion Master Kits page here.
Yes to both! The Killshot 2 Pro EFI System is compatible with both blow-through, draw-through, and nitrous applications and is also compatible with E85 Fuels. The Killshot 2 Pro EFI System's MAP sensor can be scaled for up to 26 lbs of boost and can be set to retard timing.
Note that for boost, the system is compatible, but cannot control the boost. You will need to use a separate controller for things such as wastegate control or solenoid activation. Use of these features will require manual tuning.
just upgraded from Killshot Gen1 to Killshot Pro 2 for couple reasons. 1 Being needed to have drop down air cleaner for my 454 big block stuffed in a 69 Camaro. 2. because I have total faith in this product.
Still using my 7inch display just set it to Gen2 and it works great
As always was a breeze to install and Love the PDM was a great idea!
Set up for auto tune fired right up first try. Drove neighborhood for 15 minutes then got out on faster speeds 45/55mph for a while hummed along fine. Cruised back home shut her down fired right back up with the turn of the key next day drove to a car show about 20+ mile one way cruised around 70ish :) sat at show for a few hours then cruised home worked great.
Went out this morning fired right up after a few cranks!!
Thanks Again Very happy with the product and your service also.
Didn't ship the complete order, I've reached out to customer service. Had on response that it would be looked into. That was over a week ago. I've sent several emails since with no response....if this is the support I can expect, I'm considering returning the whole kit for refund.
Aces killshot 4 bbl efi. System arrived promptly, quality appears excellent, even packaging was excellent. Tech support was great very courteous and professional, overall I am extremely pleased with the purchase and experience. Thank you very much
Installed it on our 69 mustang Mach 1, Super good quality very impressed. liked it so much I bought a blackjack distributor for the 351w, 2 high rollers and a fusion kit to go on my 67 mustang coupe with factory 390. If I Had more cars that needed them I'd buy more. Highly recommend.
Finally got to try to start my 351w sleeper build. I could not get it to start using the "race cam" in the wizard. I have a edelbrock 7182 cam equivalent (.498/.520 224/234 .050 and only 10" vacuum at 1000rpm. Had to put it to stock cam to run. My msd distributor gear height was off and caused the distributor to move 22 deg off. Couldn't figure it out until I seen all he plug wires move and engine sputter and die.
Waiting on New distributor gear and we shall see how she runs. Building my timing table now so she should run great i hope!
I think the Killshot TBI is great. It is simple to install and even had a fuel pump relay and fuse. It looks great and setup was simple. There are downsides to it. EFI is loud and this thing is especially loud. The injectors make a clicking racket that is loud enough to hear inside my truck. (1976 Dodge D100, 5.9 magnum, carb intake, tube headers, 5 speed, 3" single exhaust) Next big mod: sound insulation on the firewall!
Super clean and easy to work with it’s for sure a total upgrade
The best kit I ever bought. The instructions are very clear to read. And for the price, it’s the best. I highly recommend.
Looks exactly as in the pictures! Its well built! Delivery was fast! No damage to the contents inside! All the 8 boxes were packaged properly. Now Im just waiting to test this product in my vehicle. Overall great product so far!
Wasnt on the vehicle 3 weeks and already having issues with ecu. Customer service is horrible, just giving the run around.
Great product cant wait to install everything looks well made
Just what I wanted thanks
Killshot 2 Pro “Back to life Kit” plus in Tank Pump and Evil Energy Fuel Cell swap
1968 Chevelle 383 Stroker
Build quality seems solid. Takes a lot longer to install when youre solo, so plan on a weekend project if its your first EFI install. Pretty impressed with the overall performance and simplicity of the wiring and PDM. However, my kit is missing the the bluetooth module.
Would have been 5 stars if the instructions mentioned the PDM wiring… maybe they do but my kit was missing instructions and had to download from their website.
All things are possible through Youtube and ChatGPT.
can i use my stock distributor. it has control module in it. its on a 94 350
Great kit worked great replacing my TBI on my 1988 Silverado
Everything was packaged well and arrived early.....very impressed with aces and can't wait until spring when I can install my unit and try it out.
Its what I wanted thanks
Working well so far!
Great packaging, all parts look awesome. I won’t be installing for quite some time, just wanted to get the sale kit while it was there.
Very well packaged! All parts are present and look to be of great quality and design. It will be a while before I install it as my project isn’t ready for it, but I have watched countless YouTube videos n the kit that I doubt I will have any issues.
I had parts missing from my order.i emailed customer service on 12/4 and the issue is still not resolved on 12/16. I guess I should have bought another brand.
I’ve been keeping an eye on these systems for a while, when Black Friday deals rolled around I decided to pick one up. This is my first time messing with any of these types of systems so I had no idea what to expect as far as ease of install and first crank. I bought this system for a BBC 454 large cam, AFR heads 10.5 to 1 compression, and dual plan intake making just under 600hp. I was really tired of the cold starts on the carb with the gas needing constant feathering until it was fully warmed up and a few other issues I wanted to solve. So, install actually went pretty easy. Aces has a lot of documentation on their website that you can review as well as videos to watch. I recommend reading and researching these before install if this is your first time. Complete install of fuel system and injection system took about 5 hours total. No major hiccups or issues. After install flushed the lines a few times and connected and primed the system to check for leaks.I have the 7” handheld system so I did the initial start wizard and zeroed the TPS and it cranked right up first try. It had a rough idle for the first minute but, once the O2 sensor came online it smoothed out. After that I adjusted the throttle body , did a rezero on the TPS, pulled some fuel out of idle and it cranked right up no issues held idle did a quick drive drives decent for no tune. I plan to work on the tune some this coming week. Overall I am very satisfied thus far with the system. It’s as easy as they make it out to be and seems it will fix all the issues I was having with the carb. As long as it has longevity which time will only tell I fully recommend the system . Like I say I do recommend reading all instructions that come with the system and going online to review all the documentation and videos there if this is all new to you. Their YouTube videos help explain a lot much better.
Looks great. I can't wait to install it.
