Decent value on injectors

I was looking for some high impedance injectors for my project and checked out FAST. They had a good price on a set, especially compared to other brands I was looking at. I didn't see any special deals when I bought them, but the base price was competitive enough. Shipping was standard. For the money, I feel like I got a good product. It felt worth the purchase.

Good system, slow support

I bought an EZ-EFI 2.0 system for my Chevelle. Ordering was straightforward on the website, and it shipped in about 3 days, took 5 days to reach Denver. Installation was mostly smooth, but I had a couple of questions about wiring the fuel pump relay. I tried calling technical support, and it took a while to get through, about 45 minutes on hold. Once I spoke to someone, they were helpful. The unit itself works well, started right up, and the self-tuning feature is great. The quality of the components seemed solid. Overall happy with the performance, just wish support was quicker to access.

Got my intake manifold

Needed an LSXHR 103mm Intake Manifold for my build. Found it on their site, easy enough to order. It showed up about a week later, no issues. It looks good and fit right on. The whole experience was pretty chill, no stress or anything. Just got what I needed.

EZ-EFI works well, shipping could be faster

I decided to upgrade to the EZ-EFI system for my hot rod. The system itself has been excellent; it made a huge difference in how the car runs, and the self-tuning was really easy to set up. I appreciated the detailed instructions that came with it. My only real gripe was the shipping time. It wasn't excessively long, but I've definitely had faster deliveries from other online automotive stores. Customer service was fine when I called to ask about my order status. Good product, just plan ahead for delivery.

Thinking of upgrading to an XFI setup, but like, is it really that much better than say, Holley Sniper? Heard mixed things on tuning difficulty.

T Todd Romero 2 months ago

From what I've heard, XFI is more advanced, especially if you're getting serious about racing or a really specific build. Sniper is good for a basic swap, but XFI gives you a lot more control. Holley's got good stuff too though.

R Rachel Marsh 2 months ago

XFI is definitely a step up from something like a Sniper. More features, finer control over tuning, but yeah, it's probably not as 'plug and play' as some of the simpler systems. I think a lot of it depends on what you're trying to achieve with your engine.

hey, anyone know if FAST does military discounts? looking at an EFI system for my camaro and every bit helps.

R Raj J. 3 months ago

Yeah, they do actually. I remember seeing it mentioned on their site or in a FAQ somewhere. I think you gotta prove it, like most places, but it's def an option.

A Anna A. 3 months ago

They offer it. Pretty sure you just need to contact them directly or maybe apply through some ID verification service linked on their site. My buddy used it last year for his intake manifold.
