am i hitting fuel cut??

i recently put a catless dp on my 07 wrx. i now have tbe with the cobb ap. i flashed to stage 2 and i didnt feel right. thought that it would just take a while befor it would really kick in. after reading further i think it might be fuel cut. between 3 -5 gears when it hits about 3to 4000 rpm it just kinda bogs out it wants to go but it just wont. what do you guys think. if it is fuel cut what can i do about it as fast as possible beacuase i heard that is not good for your motor. what do i do

i thank everyone for their support on this problem

if you have the dough, go get tuned.

if you don't have the dough, sell your catless and go catted.

i just went stage 2 recently, boost creep like crazy with my perrin catless. traded for a helix catted and now no boost creep.

it won't hurt anything as long as you don't hit the cut. for a week or so i drove like a granny. you can pretty much punch it in 1st and 2nd, that's plenty to get you ahead on city streets. on the freeway though, don't try to pass up cars.

Doesn't sound like fuel cut or w/e. It's usually accompanied by a harsh 'jolt' to your car, followed by CEL and you won't be able to accelerate for a couple seconds.

Maybe just a loss of power in that range?

You can easily install a turbo with a friend, and either look on cobb's forums or email tech support about getting you a vf43 map for a stg.2 '07 WRX and you'll be fine.

Characteristics of the small 13T turbo you have is fast spool, but they drop off fast. I'm guessing that's what's happening to you. I highly doubt your car bogs down while driving WOT 3-5th gears.

does your car jerk like crazy, followed by your cruise light blinking?

I doubt it's running so lean that it's slowing down. It's hard to diagnose it like this without seeing it. Maybe you're only running wastegate pressure (7-8psi)? I'm not sure.
