Hey Bernie.

Well, I popped my 7M-GTE in with the stock ECU, Lexus AFM (stock screw in stock 
location, so the bypass is exactly where it was.) and 550cc injectors.

Yes, I should get an extended screw and close off some of that bypass.  My Check 
Engine light will sometimes come on at hot idle, reading an AFM code.  I suspect 
that this means that the AFM is reading lower than the ECU believes that it can 
with the engine running.  It goes out as soon as I give it some gas.

Other than the CEL, it's not giving me problems at all.  It takes about 1/2 hour of 
running in closed loop mode after resetting the ECU to learn the fuel map, and in 
that time, I drive it "nice" to let it learn.  I keep it to about 1/2 throttle, 
which still lets it boost, but not for extended periods.  (I'm paranoid about 
running it lean.)

I have not yet measured fuel pressure, so that's hard for me to compare, but it 
seems to run well.
