Not sure if i understood you correctly, you mean press reset adaptation after every tps (device) adjustment? For sure i haven't done it always, but after any map change i press reset adaptation... just in case.
Am i missing some step?

causing this strange behavior??
Can't be 100% sure, only if something microscopic but i've removed the TB's to check the intake boots, and all piping related to MAP sensors. Both have been thoroughly blow with compressed air.. no signs of any kind of blockage.
Yes TB's appear to be synched, relying on tuneecu map info, these are less than 5 units apart from each other.
