based on your last response after i gave you information, it sounds like its not a consistent problem but off and on.. its the spark plugs or the ignition system failing most likely. hopefully its not the fuel pump or injector related.

It is active. I will deactivate it. Since I did change the spark plugs at the same time I replaced the cams I will change those out also. I think we are getting to the bottom of this.
if you try to lift shift with NLTS activated the car will freak out inbetween shifts.
dont ask me how i know.

I dont think you mentioned what coil setup you have, but what you are describing is fuel-cutting, not plug/coil problems. I think tsc is on money re NLTS.
Mind you, if you are running those numbers on the stock coil setup, well I guess you will find the limits soon, hehe.

It's probably your spark plugs. I had the same thing happen to me, it kept cutting at 5500rpm. I thought it was the ecu. I made a fresh rom copied over the maps. Nothing still fuel cut. I thought my licp might have been leaking, changed it. Still fuel cut. Thought my pump was going out, changed it. Still fuel cut. I never suspected the plugs because I just changed them about a month before all this happened. Changed the plugs and the fuel cut went away.
Doesn't hurt to try the cheapest route. spark plugs.

Well this was the problem. 
for 3K. I couldnt believe it. I installed some iridium plugs and now it pulls to redline without any problems. I know what it feels like when the gap is too big and it breaks up up top but this was like I was hitting a wall. Im also not sure why this would cause my afrs to sky rocket when it happened. You would think it would go rich
. Well either way its fixed. Thanks for all the help Raptord, Tcomp, Merlin, Burgers, and of course 3K
Awesome, glad you got it sorted out. I know, who would have thought spark plugs. I was scratching my head for 2 months trying to get my fuel cut issue fixed. I made a lot changes to my rom, changed parts. Nothing. Googled fuel cut, most of the issues dealt with boost cut, load cut. But a couple said to change the spark plugs, tried it. Well whadda ya know. Coulda saved me alot of money. ha ha

Well the problem is back
. Since the problem got fixed with new spark plugs obviously its an ignition issue. I bumped my spark plug gap from. 023 to. 021. Hopefully that takes care of it.
