I'm pretty sure 15-16psi is max on stock fuel system. Atleast thats where i was hitting fuel cut.

 

[boostedgsx4]

yeah thats rite.

but i never ran on race gas i heard you dont really hit fuel cut if your usin it.

I dont think hitting fuel cut has anything to do with the octane that your pushing. Has to do with the amount of fuel needed. 20psi on stock fuel system? I doubt you will run smoothly. Heck with the 15psi your running now with race gas and a decent tune you will ###### still see a difference. Keep us posted and GL =]

15-16 lbs of boost is what you can run on a stock fuel system. I know this kid in my town that ran 21 on stock fuel and couple of mods and evo 3 16g and everyone told him to turn it down or it was going to mess it up and he wouldnt listen and end up blow the motor within a month later so i would upgrade fuel if you wanna run that much lbs or maybe even a tune.

Yea i think it's a bad idea to try and drag all out without really taking care of the supporting mods. at very least you need to rewire the stock fuel pump but you should really just get a walbro 190 or 255/ some new injectors and something to tune with
