Does Any One Know What the safe psi i can raise my turbo to with a 99 audi a4 t q

 

I am assuming you have a k03 becuase youdont state otherwise in your sig. Well, with your APR chip, it is basically maxxed out. i dont believe that this turbo and go any higher than about a 21 psi spike. with a chip, it is going ***** to teh wall. i was on a 10 minute drive, in a 25 speed limit place (granted i was having fun). i got home. opend hood. and my turbo was glowing. i didnt go over 40 mph. but i just got there fast. lol. if you want more boost. get a bigger turbo. like a k04

 

stock boost unless you have programing to go with it
