Peter might want to chime in to explain why his power curve is so much flatter than others?
My car is suffering the same fate with crap power curve
Well pretty much, but have a look at the whole curve he is making more power everywhere also (not just peak power)
My car is a manual which sometimes yields higher results, another 335i with just a procede and AT was ~ the 210kw mark by memory.
