Don't get worked up over the dyno numbers. They are way too many variables. I put down 320 in 90 degree whether one day, and the 314 on a similar day with the SAME mods but different dyno. Both dyno's were Dyno jet, but one operator ran the car up to almost 150 mph and the other punched it in 3rd???? Today was much cooler, but more importantly, I could feel the difference in the car with Jerry's new tune and only put it on the dyno to check A/F. I was not expecting to see an increase as big as I saw! The real measurement is at the Track!!!
