Quick question on NLS and weird noise
I have a hhr ss with a 23 psi trifecta tune. I was practicing the nls tonight and had something weird happen. I went from first to second and right when it went into second, the car stopped accelerating and made a farting sound. I let off of the throttle and everything was normal after that. I dont know what it was, but it couldnt have been good. Does anyone have any ideas on what could have happened?

It was misfiring,
The engine was may be too cold, or you nls too slowly.
I had that happen when i got my tune, it was cold outside, now with warmer weather its fine.
May be it was my bad a couple of times not shifting quick enought though... i was kind of afraid to push the car too much with the tune...

Make sure that the car is fully warmed up and you shift FAST!!

The 1-2 NLS is hard to pull off consistently - it happens so fast, and the tach lags a bit. It's normal to get a POP-POP sound though. I usually do a normal shift from 1-2 (the NLS doesn't seem to save any time because I just get wheelspin anyways!), and then NLS from 2-3 and 3-4. Anyone who's doing a NLS from 4-5 is going way too fast
