I installed a Power Commander this morning and noticed that the popping has gotten quite a bit louder with my Staintune and K&N Filter, especially with decel or when shifting at high revs. During one shift it almost sounded like a backfire. I'm going to try plugging the PAIR valve next weekend to see if that helps. If that doesn't do it, I'll try a higher octane fuel. I'm currently running 87.
