We reprogrammed this 2008 Mercedes CL63 for the owner of California Wheels, Tommy, in the Bay Area some time ago. Gains strictly from the ECU tune are 32hp & 28lbs tq. Common features of the tune along with increased power are: remove the speed limiter, raise the rpm, remove the hesitation/flat spots, improve the throttle response and shifting.
