ok...first if it's in the middle of a pull plugs are my first guess
nls...yesh it is bad for yer 2nd gear but it's fun. gotta pay to play
popping is a rich mixture. since you're not giving the engine time to rev down there's extra fuel in there between the 2 step or nls to make up for the ignition that the fuel system thinks it is feeding. eh sorry if i explained it bad. i'm sorta drunk lol

Lol yeah you are and no its not plugs

you're asking what the pop is between shifts? i'm sorta lost.

YelloEye · Mar 14, 2010

Well theres actually 2 questions. 1st is the multipop before I shift out of first. 2nd Q is the squeaking sound.

ff_drift_lol · Mar 15, 2010

i think you have an exhaust leak...if you're explaining it how i think you are. the squeak is like a bird chirp kinda sound, right? the pops before the shift...sounds like it could be a vaccuum problem or a bad 02 sensor. but i would just keep looking for that exhaust leak. flex pipe is a common area.

also always clean the maf when dealing with air/fuel related stuff

Exhaust leak would be all the time, not just when I'm at the top of 1st. the squeak does kinda sound like a bird chirp. Not tire chirp.

FYI the popping sound is completely normal, I'm still puzzled by the other noise

The other noise is the BPV farting until it seals. Since tuned on the Hahn intake, I can hear it at times on a sharp release of the throttle between shifts. Doesn't do it all the time.

The pops are normal if you do an NLS too slow. 1 pop = perfect.
