Folks, per this thread I had asked for opinions on my stage 1/dyno analysis. All good (I think). But here's whats bugging me. When they gave me the printout of the Dyno runs, it had 2 graphs: top graph was horse power before and after, bottom graph was torque before and after I wanted to see the Air/Fuel ratio line, so I stopped in to the dealer the other day, he gave me a new printout, this time with 3 graphs: AFTER horse power, AFTER torque and A/F line. But the thing that’s bugging me is that the After numbers on the first printout he gave me are different from the after numbers on the 2nd print out. Curious: Why?
