okay, first off the whole ignition system is new, and the wiring is good. My problem is that when under boost and then go wot it cuts out bad. Mods are single 67mm turbo, precision 780cc injectors, emanange ultimate, profec b boost controller, ect. The car drives fine other than this problem, and if not wot, you can go to redline with no problems. Boost is set at 15lbs, plugs are gapped at .32(tried .26 with same result). All the coils are new, igniter is new, checked coil and injector wiring. If anyone has any ideas or suggestions would be greatly appreciated. thanks
cutting out at wot

yes i have wideband hooked up and reading 11.0-11.5 at wot. As far as i know the emanage is working properly, don't think the car will run without it.
how do i check or know if it's blowing out the spark? I've gapped the plugs lower with same results...
I was blowing mine out gapped at .032 running 15psi on my 2j with a T67. That was on my AEM and stock ignition though, now with the ViPEC and the LSx coils I'm running .035 gap and no problem.
I have boost leak tested the car and all is good. Also did a compression test and that was good as well. Is it possible that a cam sensor is causing this problem? I've unhooked one a time and the car still ran but with both unplugged the car doesn't run. It's raining tonight but i'll try and gap the plugs lower once it dries out.
alright, well i gapped the plugs down to .022 and still breaking up badly at wot. unhooked the boost controller, which wastegate spring pressure is 9lbs, still breaking up... i'm about out of ideas. help please!!! possible bad cam sensor? tps? causing these problems?
yeah i can hit boost with 3/4 throttle or whatever but once i go wot is starts breaking up really bad. Have not checked map sensor. How do i check it?
so the problem pops up when the throttle is between 3/4 and full open? have you checked your tps to make sure it's not giving a funny signal between those points? since you have an emanage it should be fairly easy to check, plug the laptop in, follow the directions in the manual to see that throttle voltage in real time. make sure the voltage goes up in a nice linear fashion as you press the gas peddle several times.
