Why is this throwing U1424??

stock TB, even with stock tune does it, has magnuson on it, does it with their base tune even. Thought had bad TB swapped that. Did do it orignally everything seemed fine cruising around on their original tune file, but it limped soon as you went to WOT. Done this ever since they sent revision, and even does it on the original file they sent now which makes no sense??

Try1 log is first pull where throttle worked up until it saw load on the v1 tune, other logs are it limped immediately cant get codes to clear and give us any blade movement with pedal. Wiring seems fine you move blade by hand and both respond normal/linear

Yes it was nothing I was doing I eventually found out. It was wiring buried in the wire harness to the throttle body, had to find the one wire using sorcery, and repair it with some magic
