this is an automatic correct? are you using the stock maf setup? im also assuming a stock turbo?


make sure the wastegate arm is connected to the flapper, if it is, make sure the flapper with move freely when disconnected.

check the line coming from the wastegate, and follow it all the way back to the boost source. make sure you dont have any leaks. also try connecting the wastegate hose directly to a boost source to bypass any boost controller.

a boost leak test would be a good idea as well if its been a while. could have a few small holes bleeding off boost.

if none of this seems to help anything, you might want to start looking for exhaust leaks
