Improve the performance on your 2017, 2018, 2019 Chevy Silverado or GMC Sierra without increasing your factory rev settings. HP Tuners hardware and credits included.

Supply chain issues have made ECMs scarce. Consider our ECM Exchange product for $1219.23 CAD or $951 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.
