Automatically corrects speedometer and odometer readings for non-stock tire sizes and/or non-stock rear-end gear ratios (accurate odometer readings are required by law).
Q: My 2003 sierra 2500 lb7 has slightly larger than stock size. 32.5". In addition to speedo correction, will it make any difference with shift points due to ratio changes? Answer this question
A: Hello Ostin77, For your 03 GMC Sierra 2500HD 6.6L, the design of this Speedometer Calibrator is to let your vehicle know Tire size and new gear ratio, no shift points info from device. You can update this speedometer calibrator HYP732500 to the Max Energy calibrator with Hypertech via website (I do not know how much they will charge to upgrade your calibrator). We do offer the Max Energy Power Programmer HYP32500 which will update shift points (does speedometer calibrator function plus more features). Thanks for checking us out.

Q: Will this unit adjust readings from wheel speed and VSS (vehicle speed sensor) to prevent ABS error light from being turned on? This pertaining to a change in rear gear size. ABS light and Brake light come on every drive due to different readings of front sensors and VSS sensor in center differential. Answer this question
A: Hello Gear, Yes, this will allow you to adjust the VSS. It will also clear the ABS code. Thank you for the question.

Q: So from the question previously about using this programmer on 2 different trucks, that answer was only 1 truck at a time, then this programmer needs to be plugged in at all times once truck is programmed. Is this a fair assumption? Answer this question
A: You can only use this programmer on one truck it will not program two trucks. When you're done programming you unplug the programmer until you want to change the program or put your truck back to stock.
