2006 - 2007 GM 6.6L LBZ Duramax | Engine Tuning by PPEI

Edge Custom PPEI Tunes

Loaded the PPEI Custom Tunes into Edge CTS3 Diesel Evolution with zero issues. All the tunes run flawlessly and are a big improvement over the canned off the shelf edge tunes. Working with Edge people now on how to get the PPEI TCM tunes loaded. Edge and PPEI were very easy to work with and the process was extremely quick.

Not my style to review product

Again not my style but tunes are great, fuel economy, power, and drivability has all improved. Transmission shifts are solid. Customer support is responsive and reliable.

Everything worked great and Awsome customer service.
