i love you so much i literally can’t understand **** through a keyboard i guess.Segment swap. I forgot to mention to go ahead and copy over the speedometer calibration too since 4x4 low changes how that works.
You want to move over the Transmission, Transmission Diagnostic and Speedometer Calibration.
Once you go through the swap, re open the tune and look at your Gear/Tire Wizard under the EDIT tab up top. Adjust the Gear Ratio and Tire Diameter to match your Tahoe. Leave the options checked for Speedometer Rescale and Shift Point Adjustment.
