Default issue with tps

I am having an issue with my tps going to 0% in the factory ignition logs of the utec. I am not getting any other check engine codes. I am running this on top of an ecutek and have basically made the factory ecu stupid above 3000 rpm. The issue seems to only happen when I am under boost. The car is an 04 Sti with numerous mods. So far I have swapped out the throttle body and position sensor. And even swapped out the utec thinking it was a bad utec. I am out of ideas. The unusual thing is that the car will stop doing this the more you drive it. After about 10 mins of driving the issue seems to go away. The issue is worse when you first start to drive it.

Thanks,
Dan
