Are you dealing w/a possible boost leak. Have you checked all the pipe connections?

Lets see what that CEL code is. That will certainly help.

Do you have the means to log a run & post up the results?

We'll need more info on what you have on your car and what fuel is available to you (E85?).

Sorry to complain but maybe this thread should be in the “tuning” area? Not the dyno results for sure. It just seems to be getting cluttered up over here.
