Car stutters badly in 2nd at 5.5-6K

[Colossus]

Im not sure why, but my car seems to ride really rough and sort of jerk whenever i hit 5-6K in 2nd gear. It never happened until last night, when I launched on an integra at a stop light. Whipped his ass BTW...but my 2nd gear seemed like it just didnt want to keep going in RPMs. Everything seems to be fine other than that. I did notice a bit of a cloud behind me, I figured from losing traction..but, I'm a TSi..So, AWD= Good grips on launchs. The car its a 91 Talon TSi, AWD obviously. 133K on it. I didn't burn the clutch or anything, and it still accelerates quickly. But, I'm hoping it wasnt an ECU problem which is making my ECU assume it needs to fuel cut? I've never experienced fuel cut though, so I'm not sure exactly what the problem with it is. The car still builds boost, so I'm assuming it's not a bad connection in the IC or along the turbo route at all.

Any comments?

does it stutter on all other gears @ 5000-6000 rpm?

check your sparkplug, probably time to replace them suckers...

I dont believe it does it in first...and I havent had the chance to get it that high in 3rd gear or above....to much traffic and such

Ok, tried it again. At 5.5K it feels like im hitten a brick wall it just jerks really bad I dont try to force it past that or anything just 1 hard hard jerk, with my stock boost guage super close to 14. Being the guages are inaccurate, I take it I'm hitting 15 psi and hitting fuel cut due to a boost controller being fully opened :\ . Only in 2nd gear though....b/c that's where I hit 5.5K and up....and in first I dont have enough exhaust flow to create 15 psi.

Any comments?

You have a boost controller and a stock boost guage. :thumbdown You are probally hitting fuel cut then. Thats the only thing I know of, off hand that feels like a brick wall.

Yeah.....we confirmed it being fuel cut First time Ive ever experienced it.
