AND????? Do you think you can effectively calculate the loss, given the load, tire, temperature of the fluids. Dyno the BHP and then stick it in the truck and measure the net HP and that's your number. Using a linear curve as you are suggesting will cause you to reach a point of diminishing returns which will flaw your data. That's to say, the driveline would have to be seizing.

Just as it's not a fixed HP loss, it's not a fixed percentage nor does it weigh in on this situation. The effect is negligible considering the fact that you contended that 265BHP was achievable and 253BHP was achieved, when neither has been shown to be true.
