    OK guys, i just had HADDAD MOTORSPORTS install my longtubes this week. I was pretty happy with the numbers after the headers and the custom tune they did. Here is the dyno sheet:

    I saw this on the other board.

    I still don't know what to say, well maybe I do.

    I don't think anyone else has gotten almost 100hp out of a CAI, tune and longtubes/exhaust.

    What's it run in the 1/4?

    Dyno is not off. There's a formula to get it the way most look, they just show the raw number where most show the corrected number. The formula was posted by Haddad on the other board, I don't recall it off hand.
