Improve your truck or SUV's performance and drivability with a Peitz Performance Delta tuning package! We developed these tunes with the overall driving experience in mind. Not only will you gain power at wide open throttle, but you will also feel the difference at part throttle via improved throttle response and quicker shifting. These packages are intended for stock L84 5.3 liter and L87 6.2 liter Silverados, Tahoes, and Suburbans.
In order to tune your truck or SUV, you will need to have your engine control module (ECM) unlocked by HP Tuners. We can manage this for you if you select the option to get your ECM unlocked. If you already have an unlocked ECM, select the appropriate option. You can also select the option to purchase a new unlocked ECM, but you will need to have a tool or a dealer to perform an immobilizer relearn to use the new unlocked ECM.
If you select the option for transmission tuning, you will need to have your transmission control module (TCM) unlocked by HP Tuners as well. If you already have an unlocked TCM, select the appropriate option. If you would like to purchase a new unlocked TCM, you can select that option as well. You will need to provide additional information upon purchase so we can send you the correct TCM with programming on it for seamless integration.
Once you install your unlocked ECM/TCM, simply plug your HP Tuners device directly into the OBDII Port and connect it to your Android or iPhone using the Tune Delivery Network App to upload your stock tune. Then you will receive your Peitz Performance tune!
Programming the Stock ECU with our calibration will net you up to 20 HP with just a flash! (results vary based on modifications and other variables).
** This tuning package will work on some 2022 model year vehicles that were not Global B. Typically these are the trucks that are "pre-face-lift" with the new dash display in the interior and front grill. Ask our sales team for help determining if you have a Global B truck or not.
