Get ALL FIVE Switch on the Fly tunes - light tow, heavy tow, sport economy, hot street, and race, plus a base stock tune for your 2017, 2018, 2019 Chevy Silverado or GMC Sierra. Included with this package: HP Tuners MPVI3 Hardware and credits.

Supply chain issues have made ECMs scarce. Consider our ECM Exchange product for $1089.75 CAD or $850 USD less if you can tolerate parking your vehicle for a few days while you remove and ship your ECM to HP Tuners.  We’ll provide clear instructions how to do this.  If “no down time” for your truck is more important than getting it tuned quickly, call us for the latest on ECM delivery estimates.
