After the first 5-6 tankfuls of gas I have noticed even quicker acceleration when taking off normally from a stop. The sales guy said something about the engine adjusting the fuel mixture after a few fillups but I didn't give it much thought until now. Has anyone else experienced this? My G ('08 Sport AT) feels very quick now with just a little throttle. I love it.

 

yes. i just broke 500 miles and the car seems quicker every fillup.
