i have an 04 tundra and lifted it and went from a 30in tire to a 33 in. it changed by over .1mi and the shift points are wrong.... does anyone have a product suggestion that will recalibrate the speedometer odometer and the shift points? im told this could also help with gas mileage. i love my tundra but absolutly hate the 4speed in the 04. anything that would help id try... what companies make a product like that, and whats the cheapest or best...?

Does the Superlift Truespeed actually change the shift points as well?

You can't manually change them if that's what you're asking. The ECM controls tranny shifting using signals from the input and output speed sensors so when you change tire size the ECM as well as the speedo receive an incorrect signal. The Truspeed modifies the signal which corrects the shift points.
