I'm well aware of the engine differences
150 and the 170 units rev more like petrol engines.
My mate with a Fabia vRS which I mapped is quicker to a 100 than a 2.5 Z4
End of the day a lot of it is down to how its mapped and driver skill. But you want AVERAGE power rather than silly peak BHP
Here's my 130 remapped
And my current shopping trolley
Hopefully you can see exactly how the 150 / 170 units make their peak power much higher up
