Depends on how low of gears you run. From 3.21 to something like 4.88 or 5.13 it will be night and day. From 4.10 to 4.88, not as much..

If you're in an auto with 3.21 or 3.73 stock gears and you upgrade to 35" tires, 5.13s will "bring you back" closer to stock performance. Those stock gears are gonna be chuggin' it turning those 35s.

Superchips are great for re-tuning, but you're not going to get as much better performance w/o regearing to compensate for the larger tire. What size are you running?
