Im looking at the xcal2 and had 2 questions. First question is can i set my Steeda timing adjuster back to the stock location and have this programmer work? I "misplaced" my stock timing parts, so i cant convert it back. Second question is will there be a bigger performance difference than the advanced timing seen with the Steeda TA. I understand how each item works, but im wondering if the 400 bucks will be worth it or not. Gas mileage not an issue. Thanks
