So I'm feeling a little uneasy, I took my car in yesterday for service. It's first oil change was done and my SA mentioned some "software updates", something about the heated mirrors along with some DME updates. So I got it back after half a day and at first I didn't notice anything different, however today I drove a little spirited and the throttle felt weird like i had to press it harder than before. Also there was a pop from the exhaust when i barely it revved it and now it seems to sound lower and doesn't come on as often. Is this just my imagination or has someone else on here with the N55 felt the same?? Looking for some input please!
