I'm a new member to the site but have been a long-time reader. I have a couple Porsches ('06 Cayenne and '08 Cayman S).

My issue is that I have after-market 20" wheels on the Cayman and the TPMS system is consistently telling me my pressure is either -5 psi too low or that the tire is flat, which is simply not the case. My tire gauges are right, the sensor/reader is wrong.

I've found pretty good instructions on disabling the TPMS with the Durametric tool, but it requires re-coding with the Pro version. I only have the Enthusiast version at home.

I'm located in the Milwaukee area. Curious if A: There is anyone locally that may let me stop over and use there's. B: If someone would be generous and allow me to pay shipping to borrow one.

The enthusiast version is more than adequate for most of what I tinker with. I can't see spending $750 on the pro version. I've already asked the local dealer if they'd disable the TPMS system, and that was shot down quickly.

Thanks for your help.
