I do have a few burning questions. I need a few answers to. Regarding my f6 auto. Was trying to keep things as stock as possible, regarding mods ,&tune so I went with just a stage 1 plaz piping kit.venom cat& cat pipe &middle muffler delete. Then drove 4 hrs to get my car tuned. My question is was told the fg f6's don't need the plugs re gaped , like the ba's .We did 4 runs on the dyno , and they had trouble with controlling the boost.was told it was because of the hi/flowcat & pipe.And iam going to have to do the flapper mod. To control the boost . which I didn't really want to do. Still has stock injecters &cooler. Cars been limited to 5200 rpm. To stop over boosting, any one got any thoughts on this. Or had a similar situation happen.
