KD Custom ECM programming for Duramax LB7
All tunes are built as dual mode switchable but as these vehicles age I recommend not adding a switch. The tuning will default to the lower HP level which should be plenty safe for a stock transmission. The higher HP will push the limits of the stock transmission. Typical tune sets are 50 HP econ/tow and 100 HP performance tune. DSP2 switch sold separately.
