i just talked to PDX, jarrad wasnt there but got some info. i know you were running 13.4s before and now all of a sudden the car went down hill. only you have changed is the grounding kit? you should pull your plugs to see what they look like. also make the coils look good. you are running 93 right? i left a message for jarrad to call me back. he going to help me find out if its been flashed or not. they want to see some logs before you tune it. to make sure there is no mechanical problem and that its just a tuning issue.
