The coolant temp sensor problem needs to be fixed; it's even needed with the AEM.
Either the Throttle Position Sensor and the Turbo Pressor Sensor could be a part of the stalling problem, so they should be corrected as well.
Troubleshooting steps for these sensors are all in the TSRM (Toyota Supra Repair Manual). If your buddy doesn't already have one for his Supra, he needs to get one.

i've tested the coolant temp sensor & replaced it, and adjusted the TPS only showing 78% of throttle open got it back to 100% the turbo pressure sensor was the one's on the intake and they are gone now
