the flex fuel kit and required tuning takes care of you no matter what ratio of ethanol you decide to run. you will gain lots of hp when running the e85 and it will go away when you are not.

the problem is you probably wont have enough fuel system even with the upgrades to run e85.

I have the lingerfilder hpfp, lt4 injectors and the zl1 intank pump and I am can not run over 6psi without running out of fuel while on e85. I dynoed 590rwhp on a dynojet at 5psi and could probably get another 30 hp if I pushed it to the limit. there are ways to get more fuel like a more robust low side and a larger fuel lobe on the cam. many go with meth. I am doing an over the top port fuel injection set up.
