168 mm Pulley and LET tune
I have a 2003 E55 that I'm selling. It has a 168 mm pulley and LET tune, and my mom has a red CLS55. My dad is wanting to buy my pulley/tune and put it on my moms car... Would that work? Can i just swap the ecu's out or would we have to send my moms ecu in for the tune? THANKS!
