Default FAST fuel injectors vs bosch ?
I'm trying to get some fuel injectors that would support 800 flywheel HP on a 408ci L92 heads motor that will have a turbo later on
the injectors im looking at that will work with a stock gm fuel pump for now

sizes are FAST 65lbs or FIC 72lbs or 60lbs
all rated @ 43.5psi so with 58psi they'll flow more

the FAST runs at under 400$ and the FIC's for 600$

any one got some input on this ? ease of tuning, manners on Idel,quality and hp ratings

Go with the FIC's, they come with data, and that alone is worth it.

As mentioned, the data is the big thing. Just make sure whatever you get comes with all of the injector data.

What year is your truck? Is it flex fuel? Either way you are going to have pressure drop with a returnless system.
