Okay that part makes sense, many people add correction factors to certain dyno's to make them read out like common mustang dyno's. For example a dynojet reads higher than a mustang dyno.
However those numbers seem VERY high for a stock 135i. Those seem like crank numbers not wheel numbers.
Also PS is metric horsepower. Meaning that 322 PS = 317.5 HP. Not a big difference but something to keep in mind.
