Ok, I have run some logs but i haven't sent any to the team yet. I have added drop ins from K&N, Custom Built MagnaFlow Muffler from the Guys at Henery's Muffler in Raleigh, Eibach Pro-kit and Sprint Booster. I am curious.... Should I reset the ECU/Reflash the Software and let the Tune learn with Sprint Booster on ....OR......Let the Tune learn at stock setting, then add the sprint booster. Anything thoughts on this? Or does it really not matter....
