Superchips Flashcal will adjust your tpms setting and correct your speedometer
(which will in turn correct your shift points, if yours is an auto)
I run 35s @ 29psi, and set my TPMS to 25... that way I'll know if I have a slow leak or
other loss of pressure before it gets serious.
Also, the Flashcal gives you the option of changing your running light/security beep & light flash + other settings as well.
