Ready to Turn your L5P into a Monster? 

Tuned by CTT Tuning

Fits: 2020 GM L5P w/ 6.6L Duramax

Note: TCM Tuning is not available for the 2020 L5P and can only be used on the '17-'19 Platform.

The wait is over - HP Tuners has cracked the L5P ECM and we now have the ability to offer CTT custom tuning for the L5P Duramax Platform. It's not quite as easy or inexpensive as the previous generations of Duramax trucks, however, the results are significantly higher.

This Tuning includes 3 different custom tune levels ranging from 30HP-220HP that turns your stock L5P into an absolute monster. 

You no longer need to pay a core charge or send your ECM away. These ECM's will come ready to tune, simply download the files we send you, and flash them into your truck with the MPVI2!
 

Note: These unlocked ECM's will not be able to communicate with the GM Factory Tools, GM will not be able to flash or modify your ECM for recalls anymore.

  • New Unlocked ECM & TCM
  • 3 Custom CTT Tunes Ranging from 30HP-235HP
  • Emissions On or Emissions Off
  • TCM Tuning Highly Recommended
  • The First Custom Tuning Available for the L5P Duramax
