Wot issue...Sometimes
I have an 09 ss tc. Catless downpipe, bigger intercooler, intercooler piping, air intake, exhaust, trifecta tune. 30k miles. Car runs and drives fine under normal conditions. Occasionally though im having a problem, at WOT first gear to second...Car will build boost to about 23psi then i shift and it sound like the car is on the rev limiter (missing and popping noise) and if i stay to the floor it will continue even in second gear and no where near redline! If i let off completely for a few seconds and then drive normal no issues. The car seems to be holding boost while this happens. Sometimes i have no issues though. Today it did it again, I shifted first to second around 5500 (so under the rev limiter) and it continued to miss and sputter after i let off and drove normal for about 30 seconds then was fine. Im not getting any lights when this happens either. Any ideas or places to start looking??

I actually am not NLS'ing. This usually occurs somewhere over 5500rpm. There have been times it doesnt though. It sounds like when you hit the rev limiter except it stays after the rpm drop. One time it actually shut the car down. I was able to restart without issue.

i think i no what your talking about when i was at the track i launched rode out 1st a little went to second and it sounded like my car was misfiring really bad and had a loss of power but then it picked up after awhile. No idea what causes it but were attempting to figure it out with a log on HP

Shifting too quickly causes it for me as well.. shift a little slower and it won't happen; that's been my experience so far anyways. I'm not sure, but I think it's cause there's a higher amount of boost at high rpms over stock causing this issue. Vince told me it was either lower boost at high rpm, or NLS.. I, as most others would agree, chose to keep the boost

Mine does it from 2nd to 3rd and it bugs the hell out of me. I noticed it more when its cold, but I let my car warm up for a few minuts before I even drive it should be plenty of time. It is getting colder now but I shouldnt have to worry about my car not wanting to go when I'm getting on the highway.
