I bought a used 2011 Ram 3500 that was deleted and tuned. It has the 5 position switch. Everything seems to work fine and I haven't had any problems. My only problem is that the speedometer is off and needs calibrated. The dealer bought me a Hypertech speedometer calibrator. After receiving it I found that Hypertech is not compatible with Efi live. I have found an H&S XRT Pro locally for sale. Does anyone know if this would work for speedometer calibration? They are asking $250 for it and say it needs a new SD card. I know nothing about these tuners. Is this normal? Thanks in advance for any help.
