I ran the Banks 6gun w/PDA for over 2 years, almost always on level 7 (speed Loader) It was ok, but I still managed to blow my headgaskets with it. Also it only dynoed 357 hp at the wheels. I finally got rid of that thing, and got an SCT with custom tunes from Tony Wildman, and let me tell you, the SCT is FAR BETTER, and has alot more power. I'm going to the dyno next Sat. to get some actual numbers. Oh yeah, Banks has NO tuning to your tranny, SCT reprograms the tranny, for the power, and is alot better for the tranny.
