overboost

[jakezx]

checked all of them and all is fine all i can think is change the the wastgate to a t2 one would that help?

[Dr Silvia]

its worth a try.. if thats not it the only other possibility i can think of is that there's something wrong with the wastegate inside the exhaust.. like its blocked with something, or if sourced from some less reputable companies undersized..

Also, check your boost guage doesn't bear the logo from 'the fast and the furious' or something equally as dubious. i've seen these lie before

check for kinks in pipes or check that there isn't a blockage down any of your actuator or compresser housing pipes, i had a pipe that had perished and collapsed inside, or another way of raising the boost was to use a t piece and small jets, perhaps this could of been done already,
