egt sensor for sct livewire

[tmk82]

My egt is sensor reading is acting weird on race tune and hot street.....seems to read just fine on tow tune. Idp tunes has this happen to anyone else. Also truck seems a lil sluggish to me as of late.
Could the 2 be connected.
Any tips on how I should troubleshoot this. Kind of threw me off when it worked in tow tune.

Thanks
