Hi,
Recently became an ST170 ('54 plate) owner and all in quite happy with it except for the performance. I was expecting 170bhp in a relatively small light body to be quite nippy. However, I can't help feeling short changed - the engine seems to be in good health, starts easily, good oil pressure, no smoke / noises etc, but even in 2nd gear does not want to rev beyond 5000rpm. It sounds extremely laboured when pushed hard, even though it does pull well low down. Does this sound "normal"? I understand this engine uses variable valve timing - when does this kick in and do you feel it (as is the case in other cars)?
Cheers,
Phil.
