i say shad ftw. he has tuned my old car twice. once before i blew my turbo and second after i got another turbo. the man knows his stuff and if something goes wrong he will work to fix it. as far as k-pro when a friend of mine (craig) swapped his rsx to a k20-r. he went to shad with k-pro and had outstanding results. i say shad definitly. gonna get him to tune my next project as soon as i get my ass out of the desert.
