Hot on the heels of our 2019-2020 E90 support, DiabloSport is pleased to announce expanded coverage to the 2021 model year GM gas trucks! If you have a 2021 Silverado 1500 or Sierra 1500 gas truck, we have the tuning solution you need. The Predator 2, 7222-R is packed with power adding tunes, and all the features you expect from a tuner. We even include the required ECM unlock with the purchase of the tuner!
How does it work? Once you receive your Predator 2 7222-R, you submit the PCMMOD form on our website. From there you’ll receive instructions on how to send your ECM to us for unlocking. We’ll unlock it and overnight it back to you for minimal downtime on your truck. From there you reinstall it in the truck and tune away!
Gains of as much as 45 rwhp over stock on some applications, as well as tons of awesome features and options make the Predator 2 7222-R THE choice for 2021 GM Silverado and Sierra 1500 5.3L and 6.2L powered truck owners. Once again, DiabloSport delivers innovative tuning solutions with Power You Can Feel!
