The 2 top programmers imo are the DS and SC...I have them both and I've run my fastest times with the DS and a custom cmr tune (no tcm programming)... but, with that said, alot of guys (including me) are runnin into major tranny issues (I have to rebuild mine very soon cuz of it).... I reverted back to SC and most of my tranny issues went away (altho I believe my overdrive clutch's are about toast)...so at least I can drive around a bit while I find and buy a rebuild kit...
Thanks. it's an 05' auto trans. and what do you mean tranny issues? and if there are the best out then why would they mess up your tranny?
makes me wanna stay away
