Flex fuel
Hey guys right now I'm debating to go flex fuel or not. Current mods are 2" long tube headers, no cats and x pipe, Afe Intake , ls7s cam, Mamo ported msd and tb, cnc'd heads, five angle valve job. milled .010. Since my compression isn't really up there I was wondering what the Gains would be with flex fuel. I have a 07 c6z. Currently tuned on 91 Oct because I'm in CA. Thoughts?

Have heard that it's minimal gains if any on NA cars. One of my friends switched his HCI C6Z to e85 from 93 and gained like 6 wheel I think. You might gain a little more since it's on 91 currently.

Proven good gains through the whole powerband on lots of different platforms.
If your tuner is conservative i can see single digits gains... but otherwise i would expect xxHP and xxTQ. There are other advantages like cooler burning, less noxious, smoother idle, improved response etc.
I have not run my car on E yet but have the fuel system going in now and i plan to do so on my ECS1500 car.
