Weird problem at 5000 RPM

[IWANTSPEED90DSM]

It seems that no matter how much boost i am running, if @ WOT the car will cut out at about 5000RPM. In 1st gear it's VERY violent. The car just stops accelerating REALLY hard. As if it's hitting a fuel cut.

In 2-4th gear, after 5000 RPM it makes a rev limiter type sound, but doesnt completely cut out like it does in first gear. It also takes a LONG time to build boost, despite only having the 14B.

I'm having the same problem and I think I've narowed it down to a few posiblitys. At 15psi, you guys should be running higher pressure injectors. You might be getting a sort of fuel cut. The other thing is I find my timming is now advanceing corectly. Are you guys throwing code?

INEEDSPEED: Have you check for boots leaks. I had a problem with my j-pipe, and that also caused problems.
