Hypertech tech support confirmed for me the 752501 Speedo Calibrator is compatible with 2015's.

It supports gear & tire size calibration. Also reads codes. No tuning.

Everywhere I try to buy it does not list as compatible.

Long shot here, but anyone try this unit?

Still no tuners for 2015's, so I bought this just to recal my speedo due to my over sized tires.

Confirming for others successful reprogramming/calibration.
