If you install a good aftermarket EMS, you not only get to trash your horsepower-robbing AFM, but you also get the benefit of the S-AFC, FCD, AF Gauge, and Manual Boost Controller all in one package, not to mention other benefits like rev limiter, turbo timer, O2 data logging, ignition timing, etc.

It's possible to throw enough fuel in there to cause burning in the exhaust system that will still cause the EGT to skyrocket - it looks almost exactly identical to a lean condition.

Actually, the biggest problem I see with the 1989-1991 Kouki stock turbo exhaust manifold is the double passages - you can only keep track one ONCE side of the motor, short of buying TWO EGT gauges and probes for both front and rear rotors.  BIG BUCKS!  It's recommended to stuff the EGT probe in the downpipe for these set-ups to be able to monitor both rotors, although you get even more lag from the probe being that far away from the exhaust ports...

To find out if you're tuning's right on, you tune your fuel map rich. Then do a run or two to see where the exhaust temp is at. Then start backing off the fuel until the egt levels out and starts going up. This means that you've hit stochiometry and have gone into the lean area. Then bring the fuel back up by a hair so that you're in the rich side, but not by much
