Subject: APC problems in 9000 2.3T?

I am into my second month of ownership of a 9000 CSE 2.3T (225 bhp) and aside from a couple of little gripes am pretty pleased. However, I am not convinced that the performance of the car is quite what it should be, all of the time. Some days I get in and it does feel genuinely pokey - it picks up well from low rpm and you get a nice push in the back between 2000 and 3000 rpm with the boost guage about 3rd to half way into the yellow. Other days it seems to struggle - pick up can seem poor from low revs and the shove in the back does not seem to appear so easily. It is always possible to get it to accelerate rapidly by flooring it, even when it is in recalcitrant mood, but that is not the way I like to drive. I have read on the Abbott site that a sticky APC solenoid is a common problem in 3 year old or more cars (mine is 1998) so my questions are: Should this car feel quick without having to floor the throttle? Even if there is an APC fault, would this effect the boost pressure indicated on the boost guage or does it simply regulate how much of that boost gets to the inlet manifold? Any comments appreciated Martin
