Thanks guys..i have it bumped up to 11 psi From 8 psi and every wone is like WOW. i tell them that thats not alot because i have a very small turbo (KO3)...I dont have much money to spend seeing that i go to school and work at night...But i do what i can...I know that you can also blow an engin buy haveing to much boost and not enough gas....do you think this would be a problem with a stock turbo...I would like to bump it up to 15psi,but im not sure if i would need biger injecters....
