Stage 1
The LML Duramax was built to work, but there’s a lot more performance hiding behind the factory calibration. Stage 1 brings that potential to life with a stronger hit of power and torque, giving the 6.6L a noticeably more aggressive and responsive feel from the moment you get into the throttle. The truck gets up to speed harder, carries momentum better under load, and has the extra torque to make hills, towing, and passing feel far less demanding.
Stage 1 is designed for trucks that are still running factory hardware, so no modifications are required to take advantage of the tune. It’s an easy way to give the LML a more capable powerband without changing the way the truck is equipped mechanically.
For trucks with emissions equipment removed, the tune can also be configured to accommodate those modifications.
