Hypertech Calibrator

[shakenbakeSierra]

Putting a 6 inch lift and 35's on my truck. I notice it says you need the hypertech programmer to calibrate the tires for larger size. A buddy of mine Recently put at 7.5 inch kit with 325/65/20 on his truck without the programmer and every time he takes a corner, His traction control goes off and doesn't let him accelerate because it senses he's slipping. Does the programmer fix this as well? and does anyone know what size tires you can go up to without needing the programmer?

It is one of his front wheel speed sensors. My truck did the very same thing but believe it or not after an alignment and time driving it corrected itself somehow.
