Hello guys I'm new to the group just purchased a 12 Genesis 3.8 sedan. I just totaled my Nissan Altima SR version. The guys in my Nissan and Infiniti car club are so pissed because I'm not a Nissan owner anymore but when the guys got me out on the highway w my stock Genesis I was riding right along side all the supped up G35 and G37's. What can I do to tweak the power or horses to make faster top end or acceleration so that they wont feel that my new car is a joke?
