To tune E85 or not to tune E85 that is the ?

[l3igl3ang]

Hi i found a guy out side of OK city that has a AWD dyno and can tune car's good on E85 so i was wondering should i have him tune my DSM on 91 octain or E85? My friend said with E85 u can get more boost i could do like 30 PSI on E85 and he said it burns cleaner and better for the motor! (i heard other wise that e85 was bad for motors but i dont know)

My 1997 gsx has a

2.4 stroker
rebuilt stage 3 jacks tranmission
i know its got a 50 trim turbo but no clue what brand or type it is i will get a pic of it
and i belive it has all the fuel mods and wally fuel pump
and also has DSM link. I have not did no mods to the car beside the getting the transmission.

And last on the E85 do u have to install something extra on the car to make it run e85? im all new to this stuff.

Right now the car is doing 25 psi max and it dosent hit full boost till 5 grand then i got to shift so i dont have much fun time till i got to shift gears. I need it boosting as soon as i hit the gas! its got major boost lag right now cause of the 50 trim turbo.

I would be happy with 400hp but my goal would be 500hp

Also they had something i never seen before at able raceing! they have a 3g eclipse spider with a 4g63t motor in it i cant belive they got it to work but sure enough they did.

Something is off.

You should be hitting 25psi alot sooner than 5 grand. A 50 trim is not a large turbo and shouldn't be "laggy". I'd guess u have an exhaust leak or a pressure leak in the boost piping. U need to pressuize the boost piping and look for leaks.

Could also be horribly matched piping/IC with way to much volume to pressurize? If all that is good you have serious fuel/timing issues in the tune. Either way I think U have alot of work to do with the current tune/setup before adding more go fast goodies.
