Besides raw power, what else do you notice? Do you see a difference during entering and exiting a corner? Granted the trucks are setup in the same way, you should notice the difference since torque and rpm characteristic is different... I'm more in the camp of consistency, I believe that only when you have consistency is where you can push your trucks and buggies to do something out of the ordinary to discover whether that made your lap time lower or higher... Fighting your vehicle, as such is the case with mine, makes my lap time higher since even if I did squeeze lower lap time on certain laps, it averages out to be higher...
