Are u NUTS?!..
dude all you need is a tuner, nothing more nothing less!
No...That is wrong, the best thing to do, is to pick the exoctic and beat Wolf, then save up for a Lotus Elise...this can ensure victory against Kenji...It is actually how Shadow did it...So if you disagree there's the proof and my case...
You are both wrong and there is nothing to it
