i just bought a 95 tsi awd, i dont like buying cars that someone has already tampered with but from what the guy says hes done it has ARP head studs which i verified, act clutch, eprom ecu,big 16G turbo,and few other minor things. now the problem is at full boost i spike to 20psi then settle around 18-19 , i do not know if the block has been redone or anything like that ,this is my daily driver and i dont want to risk blowing it apart. will the 4g63 be ok at 20 psi on that turbo? the wide band under full boost is bet 10-11 afr which is ok. it feels ok also no detonation or anything but id be more confortable if i could get it around 15psi max. the wastegate arm on that turbo is not adjustable like ive seen on some others. is there any other bolt on wastegates i can buy for that turbo to lower boost a bit or will this be ok??
