Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
MY17 has a different tune/program to give you more power down low compared to MY16.
Driving 2 family members 17' redlines repeatably compared to my 15' this is noticeable. Both had better throttle response and acceleration low-mid despite my louder exhaust. I thought mine was just a dud initially until one of them eluded me to this.
Had an aftermarket tune done which fixed the spongey low end response
