There is going to be a lot of hype in the coming weeks about L5P tuning.  People want to know what are the benefits, costs, process and every other detail about this new tuning product.

The L5P Duramax ECM can be unlocked and tuned
  - First your ECM unlock needs to be performed by HP Tuners ($2,499)
  - You will need to send in a stock ECM and VIN (we intended to make a limited amount of cores available) and they will send back an unlocked one
  - The unlocked ECM is not tuned, it will have a stock file on it
  - That unlocked ECM will have to be married to your truck using a combination of HPT software and GM software. VATS (Vehicle Anti-Theft Security), injector flow rates and crank position relearn all need to be completed before your truck will run properly on the unlocked ECM


You will need to have HP Tuners hardware/software to tune your L5P
  - VCM Suite 4 (Included)
  - MPVI2 ($299)
  - 10 HP Tuners Credits for the L5P ECM ($49.99 each, $499.90 total)
  - TCM support requires a similar unlock at this point along with more credits to tune
  - Calibrated Power Solutions does not have control over these costs


Our initial tuning brought the stock L5P from 409 RWHP to 502 RWHP
  - We will continue to develop our tunes and final results may vary from our initial testing
  - Once we are confident that our tunes are the best on the market, we will offer custom tuning through our Authorized Dealers
  - Pricing for the tunes will follow as we continue to develop and refine our calibrations

As more details become available we will make sure to keep you in the loop. While we understand there is a huge demand for this platform.  We also know you want it done right.  It takes time and energy to properly develop the infrastructure necessary to properly refine our tuning and support our customers through this process.
