I am curious about this as well as SOS told me the same thing. Is it just the TPS that needs to be recalibrated to be within the specifications? If it is, there was a post on Prime a while ago where one owner replaced their TPS with an aftermarket one and calibrated it with a multimeter. I removed my sensor when I thought it was faulty and just followed his process to reinstall. Now if you had to recalibrate it to outside of the listed specifications in order to compensate for the increase then that would be another story.
