Actually, the AEM might not give him a great boost of performance. What size of turbo is it?

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.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
