I'm new to the GT500 stuff, but not new to tuning. I've used HP tuners to tune many GM cars and trucks and would like to be able to use it on my GT500. Seems like all they have over on that side is the SCT programmer and some canned stuff. I'm not crazy about buying one of those and having to email someone to send me a tune. I prefer to do it myself.
Anyone have any experience tuning a 2010 GT500?
