A tune for the strong but lazy from factory M278.  Unlock more than 530 hp and 600 pound feet of torque.  Our tune on my old 2014 CLS 550 4matic ran 0-60 in 3.68s with 1 foot roll out and 12.04s through the quarter mile.

This tune was refined on my daily driver over six months resulting in one of the smoothest and most complete custom tunes available for a Mercedes.   Not only is it fast, this tune is reliable with over 50,000 miles logged many of these miles were in hot bumper to bumper traffic, and extended high speed cruising in the brutal Florida summer heat.
