01 / GM + VATS
Keep the original truck running—or make the engine work somewhere new.

02 / REMOTE TUNING
Already have a device? Buy the tune.
Own a compatible MPVI or RTD-family device? Purchase the calibration separately. Need hardware too? We’ll point you to the correct interface.

The proven work
GM tuning.
Three clear ways to buy.
Trucks + SUVs
Silverado, Sierra, Tahoe, Suburban, Yukon and Escalade—gasoline and supported Duramax applications.
V8 performance

Built by the tuner
The person responsible for the calibration stays close to the order—from the first compatibility check through the finished tune.
Hardware when you need it
Already equipped?
Just buy the tune.
Most customers need a device, and we’ll match the right one to the vehicle. If you already own a compatible MPVI or RTD, the calibration is available separately.

After registering your device, purchase the required credits directly from HP Tuners. Requirements vary by controller; each vehicle page will state the expected quantity.
