Don't you just hate it when your car reaches top speed, drops down a couple of kph/mph, goes back up to top speed, drops back down and so on and the AI ends up getting you? Well, I was mucking around with the settings of one of my cars before doing one of the manufacturer events. You will need a 'Fully Customiseable' gearbox for this...or at least that's what I buy. When in the settings, press L1 to switch from the changing parts section to the changing settings section. Go down to the gear section and take the Auto Setup slider right to the right. Now should get amuch better top speed and none of that dropping down and boosting back up crap. Example: I could only get about 349kph/218mph out of the HKS Drag 180SX before I done this trick and it kept doing that dropping down -- boosting back up crap. When I done the trick I got 408kph/255mph out of it!
