Goddamn. Pick up a book. I'm tired of reading your uneducated posts.

Edit: For clarification, there is no gain doing a dyno. Unless you mean the expensive tuning time that generally goes along with the process of NEEDING a dyno. Dude, you're like me and you're like 75% of the people on this board, so let me spell this out for you boltons DO NOT need dyno tuning. (You K-Series Hondata guys, spare me me, we're talking about F-series and under 200whp heh.)
Please, and I'm honestly begging you, do research. Use common sense. A dyno does not "figure out" maximum power and torque, it provides a tuning graph to figure out weak points in your powerband and retune accordingly, most of this has to do with A:F ratios. Anyways, RTFM.
