I just got the reflash today from the dealer. Now this car has become a fun car to drive. I was beginning to think that, I spent all this money on this supposedly fast car but I will need to spend more to actually feel that. Although the update was mostly to fix the idle problem and high RPM hesitation, it did provide a power increase and the top end isn't useless anymore. The car is now giving me the satisfaction feeling I should've had since the beginning. I will follow up with any differences I notice in MPG but right now I'm just trying to enjoy the car as much as possible by revving it all the way up to redline, it just feels soooo gooood.
