It's the 2.0 Zetec 16V, the original not the Zetec-E. From what I can find (the 'original' curves on tuning sites) it has a fairly flat torque curve in any case.
That's very true. 'If'.
Since it will still pull well if I floor it at 85 in 5th, I think it can afford to lose 'some' revs still.
But it all looks too hard to change it anyway, so what the hell. I'll turn the radio up.
