Well just on this site you have a hand full of guys doing mail order and live tunes. I believe NP does something called a hot rod tune for like 150$ which is just about as cheap as you are gonna find or you can pay for lifetime retunes for 300 and he does good work. You send your info he sends you a tuned PCM and you send back your old one. He runs this site and prolly about half the guys on here have had or currently have one of his tunes.
