Just wondering how much boost my setup can handle on rtek 1.8? Its an s4 stock turbo?

the rtek ecu can sense up to 1 bar (14.7psi), but in your case teh limiting factor is your stock turbo.. i wouldnt run more than 10psi if you dont want to blow out its oil seals

Thanks, Just wondering because I have really bad boost creep, so I ported the wastegate to were the flapper is barely covering the hole. But today I was driving it seeing if it would hold boost, and I took it all the way to 14psi without realizing. Just worried I might have hurt the motor. I guess I will have to port it some more and weld a different flapper.

prob didnt hurt the motor seeing as the stock turbos dont move alot of air.....
