We at Diesel Power Products offer you pre-tuned EFILive Autocals for your Duramax from Anarchy Diesel. EFILive, by itself, is a great tool, for those that know what they're doing in terms of building programs, or files. However, for those that have not attempted this, it can be a near impossible task for most, and the potential for causing major engine damage is very real. Anarchy is known for being one of the best tuners in the industry by creating remarkable horsepower gains that deliver impressive fuel economy gains, as well.
For stock transmission trucks, they will typically net around 400 RWHP on LLY Duramax's, where as LBZ and LMM's will typically net 425 RWHP. But for the true enthusiast with a built transmission and lift pump, 490-525 is very attainable, and that will only go up with additional engine modifications, such as turbo, injectors, and injection pump upgrades.
We recommend adding a DSP5 switch that will allow you to change power levels on the fly, please select from the appropriate menu below.
NOTE: This is a custom tuned product. In various situations, you may receive an
error code when attempting to load the AutoCal onto your vehicle. In most of
these situations we will need to update your stock file. If you have any issues,
please contact us with error code messages available so we may promptly resolve
any issues you may be having.
IMPORTANT: LEGAL IN CALIFORNIA ONLY FOR RACING VEHICLES THAT MAY NEVER BE USED, OR REGISTERED, OR LICENSED FOR USE UPON A HIGHWAY.
Please fill in all of the below information to the best of your knowledge. We must receive an accurate Vehicle Identification Number or the programmer will not accept the tune. Any other false or inaccurate information could lead to the tune not performing as intended.
