I agree, however, I don't know how more direct I can be. Take it to that dyno and if the owners/operators are trained properly they will be able to give him the drive train losses. At the same time, he can check his air/fuel and ignition advance to see if he is in a safe area. Its amazing the differences a car will show on a real world load (that dyno can support real world load) as opposed to what you will find from a dyno jet/mustang tune. How many times have you heard the old adage: "We just finished the dyno tune and we have to go clean it up on the street/track”? If you have a dynomometer that will simulate every single load site on a fuel/ignition map, why would you need to do road tuning? Sounds safer to me and it IS more accurate. Let’s dispel some myths while we are at it, and get some actual REAL info out there.
