usually when ppl get a car tuned that is boosted they have 2 preset boost levels a low and a high? I doesn't make sence that he has a tune with only one preset boost level. All the places around me with do a hi/low setup???

Agreed but If you wanna know... call HKS they will give you a figure on the MAX BOOST you can run but be warned... If it is tuned don't touch it let a tuner do it for you.

You could do it 2 ways smart and redneck...Smart- get it tuned to the boost your looking for.Redneck-crank it up and let that F**ker eat

I have seen on Aussie boards that running 15-20 psi is where the GT2535 makes power. But this should be done by some one who knows what they are doing. There has to be enough fuel and not too much timing because with the 9:1 CR on the RB25 it will blow pretty quick.

Not trying to be funny but you never cease to amaze Kamin. I totally over looked that fact. That is true too just case that turbo can handle XXX HP the motor might not so if you do it the redneck way you'll blow it up, if its tuned do like Kamin and I say LEAVE IT ALONE!
