Hummer remote ECU tunes
Every Hummer model below is supported by HP Tuners, so we can tune it remotely: you read the car with your own interface, a tuner builds your calibration by hand and sends it back within three hours, and you pay only once it is delivered. Stage 1 is $250, Stage 2 $450 and Stage 3 $650.

Before you order
What you need to tune a Hummer
- An HP Tuners interface. Any MPVI2, MPVI2+, MPVI3 or MPVI4 works; we recommend the MPVI4 if you are buying new. Our guide covers buying and setting it up.
- HP Tuners credits to license your car the first time you write a tune. The table on each model page lists the credit cost.
- Your stock file and a datalog from VCM Suite, HP Tuners' free software.
