Took the 4/4 to a rolling road diagnostic place today because I was a bit concerned that she seemed to be hanging back on overtakes etc.
Apparently she is down by 15 bhp mainly, they say, because she's been driven so sedately over the last 5,000 miles since new.
They recommended a few months of pushing the revs up to about 4,5k and driving her a bit harder.
They reckon that, if this doesn't do it, they can change the throttle body for a 2.0 version (mine's 1.8) etc.
They say the cat doesn't help either.
For the time being, I'll try pushing her a bit more as they reckon this might just do it.
Anyone else had this issue at all?
