TPS tap causing REP

Tapped the purple wire at the TB for TPS signal for NX window switch. Truck goes into REP after driving for a few mins. Unplug my tap and the truck drives fine. How do I get around this. I need TPS for nitrous. Anyone have similar issues??

Idk if the controller is the issue with yours but that NX controller did the same **** on a 2014 Denali I just put nitrous on. Swapped out to a NOS controller and didn't have that problem again.
