wish i could put on one mine. i have to get a entire computer.
i have driven a CTS with the edge kit on it and wow. crewcab long bed dually was spinning in circles, fishtailing, anything with ease. like i was driving on ice. and it was set in the race mode, not the extreme. so edge gets my programer vote.
but if your wanting more than what a programmer can give you i'd have to say banks for their hard parts like their twin turbo dmax setup.
