Customer Reviews
Good deal, minor shipping wait
anyone else grab a Wildcard EFI? shipping took about a week to canada, but the unit is great.
Decent system, but be ready for a wait
ordered the Jackpot EFI System a few weeks ago, was pretty stoked to get it installed on my old muscle car. the system itself is pretty solid, seems well-built and the instructions for setting it up were actually quite clear. definitely gives those Holley or FiTech systems a run for their money on features. the only real bummer was the shipping, it took about ten days longer than the estimate, which was a bit annoying cause i had a weekend project planned. other than that, no complaints about the product quality.
Solid ignition upgrade!
Compared to MSD, the Aces High Output Ignition Box works great, though getting the military discount applied at checkout was a bit fiddly.
Another great Aces EFI order!
Just received my 7-inch Digital Dash yesterday. This is my third order with Aces EFI and they always get it right, just like when I grabbed the MAP Sensors a few months back. Shipping was fast and the product was exactly as described. Plus, I saved 15% with their recent holiday code.
Great value, even better support!
I grabbed a USB Tuning Cable during their last holiday sale and the discount made it a real steal. What really surprised me was how good their technical support is for installation. I had a question about my Transmission Controllers and they walked me right through it.
solid parts, iffy shipping
ordered my LS Swap Harness last week, it's good quality like always but took 11 days to arrive.
BlackJack Pro and 7-inch Dash
I ordered the BlackJack Pro EFI along with the 7-inch Digital Dash. The ordering process was simple, and everything arrived well-packaged. Shipping was pretty standard, took about a week to get to my garage. Installation of the BlackJack Pro was pretty smooth, and the dash integrated perfectly. The tech support I called for a quick question about wiring was helpful and got me sorted without much delay. My only minor point was that one of the wiring harness clips felt a little flimsy, but it still worked. The system dramatically improved my car's drivability. Really happy with the quality and the features.
Decent kit, minor issues
Purchased a Killshot TBI System and it's been mostly good. The performance boost was noticeable, especially compared to my old setup. Shipping took about 5 days to reach me, which is average. My main gripe is that the instructions could be a bit clearer in a couple of spots; I had to re-read them a few times. But overall, for the price, it's a solid choice for an EFI conversion.
Good system, easy install
I got the Jackpot EFI System for my classic. It was pretty straightforward to put in and got my car running way better than with the old carb. Shipping was quick too, which was nice.

Hey, thinking about grabbing one of their EFI kits, maybe the Jackpot. Does anyone know if they do any kind of special deals for first responders? I'm a paramedic, would be sweet if they had something.
Anyone ordered from Aces EFI recently to, like, California? Wondering how long it takes to actually get here. Trying to plan my install weekend.
