Thanks for the info. Per a previous response I would opt out of switching the maps for the cruise control and run just one map all the time. When you did run the NA what was one of the most significant changes you noticed on your car?

Well I'm not quite sure how to answer this as I don't know specifically what your asking? I was running rich before my tune and the tune was able to get my afr to where it needed to be with the parts I had as well as smoothing out a few dips in the power band. 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.

Great info, just what I was looking for. I am in GA now and Z1 is the place I will be going to for any work. They have a great rep in the are and Jon there is the bomb. Thanks again for the info.
