**I need somebody to double check my work...I think my math is wrong somewhere..**

so I've been working on a spreadsheet to take some data from a vehicle's data port...

and to transfer it into a Horsepower chart...

basically making a street Dyno...

I've gotten everything to work together...including graphing

but I know that my math has to be wrong somewhere and I need some help to get it right...

I think I've done all the conversions correctly...

I know I've done all the lookup from my data page correctly...

The Data I used is from a vehcile on the dyno...this vehicle made 447HorsePower and 396 Torque

but my excel math seems to say it s a lot higher...a lot higher..my end result is 25% or so higher than what it should be...

I've even added in dyno correction factor that every dynomometer uses to get an SAE corrected valueMy link to my excel spreadsheet...in a zip file...

too big for me to post it...
