Hi..Maybe you can give me a matter what I replace on this car.(except turbo charger)it is still over-boosting at about 4000RPM when you lay into it.It will not if, you go there gradually, but if it is an emergency, and if you have to get out of your own dumps..I undserstand that on a 944 sometimes the rubber out line off the waste gate leaks..but I have none..Our vent line is pinched off on these only dumps into the exhaust..The re-building on this car has been VERY say the least..Can you give me a clue as to where else to look?..I have changed tons of limiter switches..they all do the same thing..oil is totally clean..etc...Much Thanks for your time!!..Really!!
