Default Estimating HP in MegalogViewer

I see there is a way to estimate HP through MegaLogViewer. Can someone help me out with the numbers that i need to put in?

I am not sure what the first number is (TP)
Weight i can figure out
Tire diameter i can figure out too
what about the final drive ration and transmission gear ratio?

Thanks

um well i gues you could run the time to reach x rpm from y rpm and find your figurative speed increase given the gear ratios. And factor wieght to see net energy needed and then convert the watts to hp. Or you could take it to a dyno most of them have 50 dollar 3 pull specials. How is your car running?

dont bother. it wont look like a dyno curve at all.

the only thing it's REALLY good for is back to back run comparisons.

Thats kind of what i wanted to do. I wanted to see how much of a difference a few psi makes. But dyno say its a significant different. But i would like to see it on a graph of some sort. I should try my Iphone Dynolisious app.

The car runs good. i put a MBC in and bumped up the boost to 8.5psi and i can for sure feel the difference. I am bringing the car to have it tuned on Friday.
