SCT dyno session and chip burnt turned my car from a warm start surginge pain in butt to a pleasure on the street....drivability was better by 100%, just a joy to drive now. Along with that I picked up near 20 RWHP and almost that in torque by the time I was ready to leave with a 94 octane program.. Was it worth it...very much so...more power, better driver, just a really good time overall. I went in thinking my car was dialed in well...left knowing it was.
