Raising the question to those who have a real-world experience in this comparison.

Given all hardware elements, engine, sensors, Etc. are are healthy and functioning as they should, using a proper WB measurement tool (I.E. Ballenger AF500 + Bosch / NTK sensor) / PROLInk into HP Tuners.

How close is the correlation of the logged data and the actual dyno results of Power and Torque?
When calculating by the formula of:

Engine Torque (taken from "Delivered Engine Torque" or "Engine Torque" VCM channels) x RPM / 5252 (constant #) = CHP
Then applying the Drivetrain loss depending on Transmission type, Auto / Manual to get the R-WHP/TQ

Does the result of the calculation come close to the actual dyno numbers?
