Oh wow I didn't realize so many of you didn't know it had NLS. It most certainly does. Come on guys even the Chevy Cobolt SS, HHR, Caddy CTS-V, Buick Regal GS has it.
You have to be in Sport or Track mode. So if you ever tried it in Touring then that would explain why it didn't kick in. Just like in the Vettes you have to get the RPM's higher than 5600.
The best way for me to describe it. When I hit about 6k I keep the foot planted on the gas pedal and the moment I step on the clutch the RPM's do not shoot up to the Rev limiter. It just sorta stays right about where it was before the shift. The exhaust sounds different for a split second during shifts too because the PCM is cutting Spark.
