fitech EFI HP Q's
« on: January 07, 2017 - 04:23:07 pm »
I'm contemplating fitech EFI this spring. I have a 408 SB stroker. It's about 400 hp at our elevation. Can I get away with the cheaper 400hp model? Or bump it to the 600 hp version? I'd like to keep the stock fuel tank and supplement with a electric fuel pump. Any recommendations?

go 600. Gives you margin for future mods.

I'm at 600 hp, and gonna use the 800 version
72 Cuda, owned 25 years. 496, with ported Stage VI heads, .625 in solid roller, 254/258 at .050, 3500 stall, 3.91 rear. 850 Holley DP, Reverse manual valve body.

1999 Trans Am, LS1, heads, cam, headers, stall, etc! Love to surprise the rice rockets with this one. They seem so confident, then it's "what the heck just happened?"

I agree. I read up on it and the 400hp model is maxed at 400hp. It would be spiking the outer ranged all day long

For sure it is better to run it at 60-70 % than near 100%
