The reason I have two is b/c the timing has to be retarded for when I am spraying which is my track application and occasional spirited driving along with other variables when adding nitrous through the motor. I just didn't want the cruise control factor to be the reason for not going uprev. In reality either software you pick, it will come down to the guy tuning your vehicle. The first time I had it done, it was a bust and I got ripped off. Second time was better but not where it needed to be b/c of lack of experience. Take it to a reputable shop, not just any shop but one that deals with our specific car. When my build is done my car is going to GA home of Z1 which I am excited about. Just remember going all N/a will only get you so far as there is still much to be found in cracking this motor.
