Since this is kind of a n00b question, I was wondering what kind of gain I can get from going 93 oct at 26psi to e85 at about 26-28psi, i made 392whp when I dynoed with no tune and about every bolt on imaginable, now with a tune I would guess im at a reasonable 430ish,

 

You would have to hope on the dyno to get a baseline of where the car is at first. I would say you could get another 30+hp from turning up the boost acouple #'s.

 

need more info then that like what kind of bolt ons and what exactly a no tune meant! i would venture to say with jumping boost a little more if your able to and also jumping timing way up with e85 you should be able to see about 50-80hp!
