how much is the speedometer off when running 33's? did you notice a difference in how the tranny shifts after the hypertech was installed?
what size tires are you running?hypertech made shifting smoother just like stock. good investment. i have 15% off coupon code (CPC15) for autoanything and i think it's expiring in 2 days. they have 1 yr price match guarantee so get it from them now and worry about the prices later.
