PPEI LML Stock Base Tune
Vehicle Applications2011 - Present Duramax Diesel Engines
With 84 base files, it can be difficult to know which Operating System goes into which truck. When the wrong OS is loaded in the truck, issues such a ABS/Brake lights, Cruise loss, Loss of remote start, and many other issues can arise.
Due to frequent emails from tuners asking how to remedy the issue, we have created this option to simply enter your vin, and we will send you a UNLOCKED, STOCK file to match whatever truck you are tuning.
Please give us the ACCURATE vin number to avoid delays on receiving your base file.
Please allow 2-3 business days for tune fulfillment.
