The high idle problem sounds like a temp sensor. For ambient air temp the only one is the sensor in the grill by the drivers headlight. They are cheap. There is also the intake air temp sensor that could be the culprit as well. Id scan it while disconnecting one at a time to figure out which one it is.

You shouldn't need a boost fooler with EFILive. That can be all done with the tune. If its connected to the wastegate connector then thats a wastegate fooler, which is just a resistor to load the circuit. Have your tuner look at Internal Flash/Turbo/Boost Pressure, Too Low Thresholds if that is stock Id lower it by 5.5 PSI. That seems to work for me with the low boost issue.
