If you buy one it's going to be for turning off the WOT restriction. .... I have a Hypertech and it isn't capable of doing anything with the tpms light and I don't think any of them can. Mine has been on for about 4-5 years, you get used to it.Just bought new wheels and tires already mounted with no TPMS.
Can any of the tuners turn off the light? Might push me over the edge of buying one!
