I think if you put a tune on it, you would never go back, I put mine back to stock the other day and it feels boring and slow compared to the tune. The ecu tune makes it feel much crisper and peppy with better throttle response and better power and torque of course. I could never go back to stock, they feel too darn good with a simple ecu tune :-)
