Can anyone confirm for me that Mack does in fact rate hp a the wheel. I have a 2013 Pinnacle that's rated at 505 hp. The driver has been complaining of a drop in power since the last time we had the truck into the dealer. Yesterday we had it dyno'd. It was at 420hp. Now the dealer is telling me a 15% drop is normal. I'm headed in to pick the truck up this morning and would appreciate any feed back I can get!
