Description
GM remote tuning package
The hardware.
The calibration.
Two clear line items.
For supported GM vehicles, this package pairs an HP Tuners RTD4 interface with a custom PCM Tuners calibration. Add one of each item below to the cart. Keeping the physical device and independent calibration service separate also keeps checkout tax treatment accurate.
Not sure whether RTD4 or MPVI4 fits you better? Compare the two interfaces before ordering.
Before you order
- HP Tuners credits are required and are not included. After registering the RTD4, purchase the required Universal Credits directly from HP Tuners.
- Credit quantity and controller-access requirements depend on the exact year, model, engine, transmission and ECM/TCM.
- Some newer controllers—including E90, E41, E42 and E66 applications—need an upgrade or unlock before tuning.
