My Evo 7 using tune A.. You can tune to other parts if you like.
I'm not sure whether it affects the car or not. Heard that there's
not much difference.. once you car reach 990,000, your handling and
top speed will increase. The prices of each part are shown
below..
Parts Change
5,000 : Exhaust Pipe
10,000: Side Mirror
40,000: Bonnet
60,000: Spoiler
