whoah now hit the caps lock there buddy ;) yea the final drive mod is awesome even with my car running in such shitty condition, I marked off some spots on a straight road near my house for different pulls from and to different speeds, most areas I picked up 1-2mph but the most notable was my 40-65mph pull, it turned into a 40-70mph I picked up 5mph in that run. The mod is definitely worth it.
