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

I'm glad Dusty agrees with me:

Please say 'hi' to him for me, next time you talk.

P.S. The current post-turbo MAF configuration could be the very reason that MAF got ruined (if that's the problem)... excess heat or oil from the turbos could easily mess up the sensor. Please keep that in mind before you swap yours into a questionable configuration...
