I've heard that his tune for the wrx sti '10 is good for the new seasonal. However, I cannot find it. I've looked at the rkm tune page, but it only has the '05. Are you people just using those numbers to tune?
I tried both RKM '10 builds, and struggled I'm afraid. I love the work these guys do, but I had far better success with Grey Cap's purpose built car. Sublime piece of work this car...
