Can i Make 350whp on 91 octane?
true.. im running e85 right now on a stock fuel system, no fuel pump.. and my 550s are giving up on me around 5-7psi lol.. i still have some duty cycles left for around 7psi but as i tweak up the injector pwi over and over its seems like it always remains lean and seems like adding fuel does nothing to richen my afrs, looks like a sign that i need way more fuel pressure to spray that very rich volume ethanol requires

Yup! U need a fuel return setup! Adding a bigger pump will help a little bit. but not very much!
Check out the ptuning ss kit! comes with pump bypass plug and rail and regulator!
