Ya - they're an Uprev Tuner as well, I believe, but ultimately it came down to convenience due to how close Stillen is to me.
Oh - Sammy @ Stillen mentioned that he just rec'd an email from Uprev saying that a new version of their software is on the horizon. He said it will allow tuners to be more efficient, thus spend more time tweaking than they currently do. Of course, this was after my seasion was done
Just an FYI...may be worth waiting for...
