I'm tuned with all the bolt ons except headers. The M370 made me lose power throughout the entire powerband. Maybe it was a bad dyno day, but the tune managed to bring it back up.

Lose power? please explain. Did you get a tune with your stock mani and then switch to the m370 and lose power? better gains with the m370?
