Had a pro-tune done by Randy with stock DP and CBE (resonator & muffler delete) a little while ago and was seeing 24.5 psi pulls with zero negative correction, car was running great and I was extremely happy. Went ahead and installed ATP DP and now am seeing -3 correction. I contacted Randy immediately and he stated that some of the aftermarket DPs can cause excess NVH causing false knock symptoms. He has been gracious enough to revist my tune and we have been exchanging logs to fix the problem.
Anyone else had experience with false knock after a DP install?
Is not having the OEM bracket creating this problem?
Do the pros outweight the cons regarding DPs? Or vice versa?
