I dynoed my car in 3rd and 4th gear and made 10whp more in 4th It also has do do with what type of dyno your using
hp = torque(at the wheels/gearing affected) X rpm/5252

hp = torque(at the wheels/gearing affected) X rpm/5252
hp = torque(at the wheels/gearing affected) X rpm/5252
I dont have a stock rear end in my car and skewed the dyno a little.
they wanted to run it in 4th and I asked to run it in 3rd because I feet that 3rd pulled harder and thought it would put down more power.I was suprised when 4th put down more power
