Could be, 'adjusted' for an insurance group or something.
Bmw's are always a little less as people quote their ps as bhp, hence the 321 ps evo never making the 321 bhp people think it should
Not sure on Fords, but even my M3 handbook had it wrong.
Makes little odds at 100 ps/bhp, but 300 it's 4 or 5 out.
Started work at 4am, so will leave it at that
