Heavy Tow ECM Exchange Tunes incl. Hardware & Credits - Duramax L5P (2020-2021)filter sort
We do not recommend this product bundle which is sold by some other companies. Instead we recommend that you purchase our Modified ECM Purchase by CLICKING HERE.
Here’s Why. With the exchange program, you removed your vehicle's factory ECM and ship it to HP Tuner's ECM Modification department. The ECM is then modified and then shipped back to you. While this is happening, you can’t use your truck, and we’ve seen people waiting 3 to 8 weeks for all this to happen. During the processing time your vehicle will not be able to operate because it will not have an ECM in it to run.
Pay $849 USD more, we ship you an HP Tuners Modified ECM within 48 hours to flash our tunes. You keep your existing unmodified ECM which is really important if you want to trade your vehicle in the future, or bring it in for service at the dealer.
We don’t sell this product, and showed it for comparison and explanation purposes. CLICK HERE to check out our modified ECM purchase instead.
