The OP asked someone to specifically run his combo on the desktop dyno. I did it. I was the only one. I get called the jerk. Lemmie tell you something. If a dyno sim program is what you have, it's a good one. It's better than nuthin. Didn't my program get him right in the ballpark of everyone elses "guesses"? Plus, it was even a little more conservative than all of the other guesses. I bet it's more accurate, too. That's why I said stuff a sock in it. Nobody else did what the OP asked but me and yet I get called names. I believe I'll think twice next time.
