I just bought a c32 amg, and i know it should be going 0 to 60 in around 5 seconds. Every time i punch it it kind of slacks, and doesnt accelerate how it should. Other times when i punch it it will take off like a bat out of hell. Just how i like it!! I was wondering if anyone knew why it is choosing the times it wants to accelerate like the beast i know it is.

Thanks you guys!
