ok first off i know this is a pain in the ass issue! but im sick of it...i know they act up bad in cold weather but it was 70 outside the other day and i was still cutting...what temp is everyone seeing it go away? should i get the pg fuel pump internals to fix this problem? cause i have the atp boost cut killer and it didnt do s*** for me. should i get a catted downpipe? (really dont wanna) or do i have to do the pg internals and AP to get rid of the cut? i also have the denso step colder plugs and they ARE gapped right. someone please give me a hand here im gettin really pissed at the car and ready to put the stock dp back on
 
Without data logging it's hard to say exactly what is causing this. With a catless TBE and CAI you are probably running too lean and the ECU cuts fuel to protect the engine. I was having similar problems and switched from MS CAI to Cobb SRI and the problem went away. You are really just guessing without supporting data. The Cobb AP may fix but I know their map notes all say that "catless exhausts may run too lean and cause engine damage".
 
it has nothing to do with whether or not your exhaust is catted or not ( i wouldnt think.. ), you just need more fuel. get a pg fuel pump, my boost cut vanished when i installed that. also get a short ram, i don't believe in cai's (lol2)
