Problem after installing fast 90 intake

Well, this has been going on for a couple of months now and i am sick of this....
I am currently running bolt ons with a tune. After installing fast 90 intake i immediately tuned it but still experience idle problem ( the type of problem where the car dies while sitting at idle after WOT run). So pretty much everytime i go WOT, and put it on neutral after (M6) the car drops to 500 rpm and friggin dies.... Because of that, i nearly crashed 2 times... 1st time doing about 140 (racing a mustang lol) and with my **** just shutting down (in neutral) and 2nd accelerating at a curve doing about 40 and the car shutting down with no power steering lol with me nearly smashing into a curb....
I've been told that this is happening because of some throttle body sensor???
I was thinking to fix the problem myself because i really dont feel like spending an additional 150-200 dollars for tunes and labor...

Could it be a fuel pressure issue, like after you finishing whippin on some stangs the fuel pump cant keep up which in turns shuts it off because there is not enough fuel in the rail to spit out from the injectors? My car has done this a couple times, and I know that scary feeling man. Thats why I bought a bigger fuel pump and now I am having issues of keeping a hose on it so that I keep consistent pressure! LOL
cars always look good up front but sucks *** diagnosing little crap!!

I would guess a tune issue.

Does it idle ok otherwise?

Lack of fuel will cause misfires/power loss up top.

I would really like to be with the car to diagnose something like this. I would check to see what signal the computer is giving the idle control motor. It should compensate for the drop in rpm.
