I got it from RPM. Not so sure I will buy from them again at this point. I never had the power plug in at all. The only wires hooked to anything were the ground from the control unit and the white wire from the control unit to the Yellow wire on the TPS. I don't understand how it could draw power but apparently it is somehow.

Take your car to the dealership and have them replace your TPS under TSB 05-14-4. I fought with my car for a month! I was about ready to give up and pull the Zex out when I decide what the heck and made my dealership replace the TPS.. that was a couple of weeks ago... and 10 passes at the track later... no problems since then!!!

Here is the TSB:

And for you guys selling the Zex... don't forget the GT kit works perfectly in the V6! WOOHOO!!!

Here's my install, including dyno sheets at 75HP and 100HP shots.. and some numbers and video from the track! LOL!

Finally got my zex to work. I had to tap into one of the wires for the sensor right at the top of the pedal. I put my nozzle in the same spot as you per your install pics. Did you try different positions. I talked to a guy at Diablo today and he said he got another 20hp just by putting it right in front of the TB. I can't imagine that's true.
