No I don’t think so; you can’t compare expected wheel dyno output to BMW benchmarked engine dyno. Turbo engines are very volatile to external factors. Heat soak, fuel grade, air flow to the engine. They are more likely to have larger swings on a dyno and its known in insideinfo from manufactures that they are producing an engine dyno rating that can be consistently achieved using lower quality fuel, some heat soak, and non-ideal air flow or air density etc. In short if you use the exact standard method BMW is using to grade there engines you will end up whit the same results.
