Description
*OFF-ROAD USE ONLY*
TUNE ONLY – Shift on the fly or Single files (please select)
The tune you need for your L5P Duramax Available for Years 17-23
This tune takes all guess work out of upgrading your Duramax for reliability and longevity. These are actual custom tunes build by a real calibrator. The current market has never been so clouded, fear no more. No more hack files, no more missing parameters, no more blocked faults and finally proper shifting.
- 17-18 trucks will still need to be done on HP Tuners. 2019-2023 will be on EzLynk platform. (so you will need either)
- SOTF is currently only available through HP tuners. If you have a 2019-2023 and select SOTF it will be HP tuners
- All L5p Ezlynk files will come in single files. It will be all Five files included but you must flash each one individually
- I know this sounds confusing so if you have any questions just email me INFO@SHOPMODERNDIESEL.com
Any HP from 0-220+HP. You can go single and select power or go full Shift on the fly (SOTF)
*** THIS IS THE TUNE FILE ONLY – YOU MUST HAVE AN HP TUNERS DEVICE or EZLYNK – IF YOU NEED ONE LET US KNOW
*IF YOU CHOOSE A TUNE LEVEL HIGHER THAN LEVEL ONE I WOULD SUGGEST TRANSMISSION TUNING, THIS IS A BASE KIT AND DOES NOT INCLUDE TRANSMISSION TUNING. THIS KIT IS DESIGNED FOR A STOCK OR IMPROVED STOCK TUNE FILE.
