I've ruled out a lot of things like vac leaks (had the boost controller ports backwards) and pressure tested showed no leaks in my piping. The car will idle, and when I hit the AC button it will jump up like is is supposed to. The car only stalls if I rev it then get off the throttle completely. Coolant temp sensor has been replaced too, which solved the hunting idle issue, but not the stalling issue.

Driving, the car accelerates like it should, builds boost correctly. It just stalls when I come up to stoplights like 75% of the time. AC on or off seems to have no effect on the probability of a stall. Anything I'm overlooking or is there an obvious reason why I'm having this issue? I'm trying to get the car trouble free before I come down there to get the car tuned.
