So I got my full exhaust put on, but have been waiting on the PCIII for a while after a post office screw up. Easy install and the Johnny Cheese map was already loaded ready to be unleashed. UNBELIVABLE!!!! He knows what he is doing, trust me. Very good guy to work with. The power delivery is smoother, but much more violent if that makes any sense. I was getting complacent with the throttle the last few weeks, but that changed tonight. Thanks for the great work Johnny.
