There's a pic floating around somewhere that shows where the IAT is in the TVS blowers vs. the MP112/122 blowers. You could try to improve the sensor placement, don't know how much work that would be. A phenolic spacer gives more room for a bigger intercooler, and more room to move the IAT sensor, double-bonus but pricey. Sensor needs to be post-blower...

I just tweaked the tune in mine...
