Can't vouch for one but i've heard if your interested in tuning just get a custom tune from someone like black bear performance of wheatley. Basically you just tell them your mods, tire size, engine, gear ratio etc. and what you want to get out of the tune mpg, performance, fuel octane you want to run etc. and then send your PCM via. mail and they tune it then sent it back or they can send you a tuned one and you ship your old PCM back for a core charge. Most people say custom tunes are betterr than programmers but there are many guys here running custom tunes that will chime in with some more knowledge then i have.
