Fittet a boost gauge today and my z20let are only boosting 0.5 overboost and 0.38-0.4 standard..
I don't have any leaks or something like that, no smoke or bad sounds from the turbo ether..
I have tried to tightup the wastegate but it did'nt change much..
What boost are standard for the z20let?
Anyone that knows what my problem might be?
