Just installed on my 04 AWD tahoe. Was wondering if i need to mess with the gear ratio feature on my tuner, ive read these size wheels can mess that up, so is there something i need or can do to prevent this. Along with transmission shift points or firmness, running the 91 octane tune currently with all superchips values. Overall tire height is 32" 5/8 inches.

No need to touch the gear portion of the tuner.

Just measure the wheels on the truck physically within 1/4" increments.

Sc values are what I would suggest until you get used to the tuning, then go back and make adjustments if you need more speed out of each gear.
