nice kill

I didn't see many (if any) STi posters in that thread so you might not have a problem. Basically the gist of the stalling was that when you braked and clutched in (say coming to a stop sign/light) and the RPMs dropped, it would stall. A lot of people firmly believe that there is something in the new map that is causing the problem.

Thats what happened to me alot when i installed a 100 percent atmospheric BOV on my supra. I wonder if these people that were stalling had aftermarket BOV's

Not sure but apparently most people experiencing the stalls were fine until the lastest AP maps (1.21+). There is a lot of speculation on what is causing it. Most people seem to only experience it when braking and clutching in to come to a stop. No one really mentioned blow off valves in that thread but I've read about stalling issues with the STi and aftermarket BOVs (or combo BPVs set to full-atmospheric.)

Not really having the "pssssht" sound doesn't bother me one bit.
