Default Stalling Problems

I recently installed my new 75mm throttle body, upper plenum, and exhaust components on my 2000 GT and sometimes it stalls out when the rpms drop down. I checked the intake for leaks and could not find anything wrong. I then installed the performance tune from the Diablo Predator and that seemed to make the car run better but now its back to the same problem. I dont know what is wrong. I was thinking that if I were to get a custom tune for my modifications it would help the problem but i dont know. Anyone familar with stalling problems?

surprisingly, it may be your air filter. Mine was stalling every other 2 or 3 stop lights. it's a cone type I so washed it thoroughly, let it dry and no problems since.

Well i recently installed my CAI kit which came a new filter and that was less than 300 miles ago so it couldnt be that. The stalling problem didn't start until i installed the TB and plenum.

if it didnt start until after you installed your TB id go back and make sure everyting is tight and nothing was forgotten to be put back on. also check your TPS.

Would the IAC throw any codes or would it just idle funny? I have a similar problem but my cousin who has like a 4k tuner checked the IAC and didnt see anything wrong.
