I like it!
My 46 Ford has a 4 barrel carb 302 with a mild cam. You could not depend on it to start. So, I purchased the Killshot Master Kit a few weeks back and had my mechanic friend install the system. I got the non-running car to him on 16 November. He got it installed and had the first start last night, 5 December. He has a lot of work in his shop. It cranked and ran great with just a turn of the key. Hoping it will continue to operate that way. Very well pleased at this point. Sure would like that FREE UPGRADE to a 7 inch screen though.

388 Stroker
Purchased the Wildcard to replace a Tri power set up... It gets finicky and hard to start.... After working out where to put everything in my 47 Ford and then just like they promised... fired right up! Working out some other bugs in the car and can't wait til spring for my instant start ups and reliable Wild Card FI !!

Best stand alone TBI system on the market
I installed the royal flush top end kit on my 1992 Chevy 2500hd with a 350 mild cam and aftermarket vortec style heads with 2.02/1.60 valves. Initial start up was fairly smooth the self tuning feature did most of the work for tuning I only adjusted the tune slightly for better startup manors but that is to be expected. I love the amount of data the 7” display has and how easy it is to read and change. I’ve used other stand alone tbi systems and aces is by far my favorite from ease of install to ease of tuning its a fantastic system. Plus you can actually get ahold of someone when you require tech support.

Deuces wild euro style
Purchased and installed the deuces wild system on my 1973 mercedes 280C. After modifying the intake to accept the two barrel pattern, the deuces wild system mounted perfectly. Once installed , the m110 fired up first try. With just a little adjustment it ran strong. I would recommend aces and I will definitely use them on my next build !

Couldn't be easier
I recently decided I was tired of fooling with my quadrajet and decided to upgrade. I chose aces since they are fairly local to me and extremely affordable. Easy install. Everything worked as advertised. Anytime I had a question aces was there to answer. I can't believe it's even the same motor! Completely woke it up. The difference in power and drivability is insane.

Awesome EFI System!
I installed an Aces Royal Flush Master Kit on my 1968 Dodge Dart powered by a 360/ T56. I followed the install instructions to a T and the system fired up with the first turn of a key. (Full install on my CrewCabDart YouTube channel) After dialing in the fuel pressure and ignition timing the car has run flawlessly. I’ve beat on the car relentlessly since the install and the system hasn’t skipped a beat. I recently took a 600 mile roadtrip with zero issues. I would absolutely install another Aces system on my vehicle!

LS C-10 Truck Swap
First the product was readily available when competitors was not. It came quickly very nicely boxed with everything labeled. Nice cloth loom. Very descriptive manual and labels. No for the company and their supporters. I got my truck going and headed to PTTS and the guys at the aces tent were amazing in support and helping with tuning. They were not satisfied until we got some issues resolved and it purred all the way home from bowling green to southern Indiana. I can not thank Bradley Woodall enough for his help. Long story short I completely recommend this stuff!!

Awesome TBI setup!
I put a kill shot top end kit on my 1971 c10. First start up, it fired instantly. This was a super easy install, the software was super easy to use. They really put a lot of thought into the whole system. I have put 2000 miles on it so far and it idles great, runs smooth as silk, starts easily and fast every time. I love that the computer is super small and can be put away from the throttle body.

this is what I needed
I got a small block chevy nothing special at all. My Q-jet was not taking throttle at all so I was trying to get a carb and my wife picked this up for me thinking it would be better than having to pump the gas 40 times to get it to start. I did have to get a late 80s fuel sending unit and a Delphi pump with a corvette regulator. After watching a few videos and a decent install it started instantly and a few trips around the block it ran even better than it ever has. If you want a no BS system that actually works this is the one.

Great product at good Price!!!!
Relatively easy to install, the wiring is of good quality and the attention to detail in the finish is great!! I'm using it on my air cooled 2180 VW and it works perfect!!!!!

Works as it should
So far it is working out really good. Paired with black jack pro series distributor on a 351w.

Great system great price
I purchased a Master kit killshot for my Chrysler 440. I am extremely happy with the results. The distributor id compare to that of MSD and the throttle body is sleek. I enjoy the whole set up and was simple to set up. For the price it is I cannot complain about anything it is wonderful.

Love It
I’ve had an excellent experience dealing with Aces EFI. The products are top-notch, everything works as expected, and if any issues arise, they are incredibly fast to respond. Their technical support is outstanding, always doing their best to help you resolve any problems. I highly recommend Aces EFI for your next project. Service like this is rare these days, and their prices are unbeatable. Give them a try—you won’t be disappointed!

Good product
After a initial setup issue caused by inefficent Amperage and spark, i have a great running system on my BUICK 455 powered 69C10' this system has already a lot of the features that Holleys latest "sniper2" just released for 500$ less.

Put on 1985 toyota pickup 22r
Put this on a 22r for a quick replacement of a carb that needed rebuilt. Took a little bit of tuning . Recommend using advanced tuning software to get best results but . It runs at any angle .Dynoed 56hp wheel stock and after 76hp wheel. With a 1.00 weather correction factor at 8k ft. Runs good once tuned in . Pulling hiway passes much better. Tuning was actually not bad once I got thru the learning curve. Put a efi throttle cable on and changed end of throttle linkage to mrgasket throttle linkage end. Worked good. Took a little porting of stock intake as seen below. Ran a walburo 450 pump 3/8 line and fuel filter. Aeromotive regulator and some an fittings. I drilled the stock manifold and tapped it to m18 1.5 pitch tap. Reads o2 perfectly
Have a question? We are here to help.
Check out some of the most common questions our customers ask. Still have questions after? Contact our customer support.
I have *insert engine of choice.* Which of your systems will work with it?
Many of our systems work with a wide variety of engine combinations. We have TBI-style systems that fit 2300 and 4150-style flanges respectively; Port Injection (MPEFI) that are designed for classic small blocks (Chevy/Ford); and LS systems for LS1, LS2, LS3, LS6, L92, LR4, and many other LS style engines.
What do I need to convert from carb to EFI?
Modern EFI requires a high pressure fuel delivery system, and compatible ignition components. You can (usually) use your stock ignition setup, but sometimes at the cost of losing out on timing control features. Check out our master kits here, or give us a call to see if your setup may already be compatible.
Are your systems boost & E85 compatible?
E85, yes. This just requires a few basic setting changes from the handheld. For boost compatibility (not control) you just need to adjust the MAP sensor scaling in our free laptop software.
