No, if you dynoed on a loading dyno the drivetrain loss is significantly higher (usually 3-5% more loss).

Without more information regarding what type of dyno you have its impossible to tell. I would bet its a loading dyno and not a dynojet type inertia dyno. Find out the type & brand of the dyno it is and report back to us, but from everything I see the car seems to be ok.

I'll pass on the characteristics of the benches used tonight. You have to admit that, apparently, your car has the same problem as me.
I forwarded the power curve at the factory Aston at Gaydon and the ratios. It's so disturbing and incomprehensible that they will send me a specialist, direct from the factory, yet this month. I'll keep you posted if you wish.

 

Well my car is literally in process of being tuned ... should fine out shortly. However from all the dynoes I have seen they are all between 290 for loading dynoes to 320 for dynojets. If they do so.ething for you let us know

no problem
For both bench of power used:
-Bosch FLA 206 (bench official Swiss approval for new homologations, more than 800 tests per year cars, approve by the state)
-Rotronics of 2009 (bench of preparer Dijon Auto Tuning which only preparations engines, including the race)
