We programmed this car for Sonic MS of Mountain View, CA and the end result is just crazy. Read our blog for the 135i and it will kind of explain what was done to this car. It was like driving a car on ice or maybe like driving a go-kart, I'm kind of stuck for words on this one. Once you put your foot down it just wants to keep going, you can hold the needle at 160mph and the RPM just keep climbing. Speak to Darwin at Sonic MS and I hope he can explain it a little better.
