Not sure where to put this so mods feel free to move. Took the regal to the dyno today for a tune. They did 3 pulls to establish a baseline. so 402 HP and 410 Tq was the starting point Over 6 - 8 pulls and tweaks along the way, jetting / timing it came up to just shy of 470Hp and 472Tq. Not corrected for temp or humidity ect On the engine dyno after the build the final numbers were 620Hp and 700Tq.at the crank. My quandary is this. The Hp suffered a loss of about 24% while the Tq was around 35% My thinking is that it should be the same loss across the board or is it an average. The engine is driving nothing except an Alt up front. All the loss is from driveline.
