The power difference is huge, the car keeps pulling and pulling, especially with the stage 2 for sure its alot more smoother than a piggy back cause especially with a DCT gearbox the piggybacks never seem to function properly. You will be pulling away from SL55 AMG's and slightly modded M3's with ease. About the code clearing, it does not have a code clearing functionality but according to ESS, the software is engineered in a way that it gives the most power the n54 can safely handle thus it gives no tuning related codes but you can always get a code clearing tool to clear codes and shadow codes before the visit to the dealerships mechanics. Just so you know, even the COBB accessport with the code clearing functionality fails to clear 100% of the shadow codes as reported by forum members so a code clearing tool is a must have in this case.
