Probably also means he's changing up too early. Keep it on boost!!

If you have had an 02 for only 6 weeks, this strongly implies that you
bought it used.
Could the previous owner possibly have installed an aftermarket 'chip'
for the ECU? That would certainly create more non-linear power delivery
curve than would stock tuning.

Re: Is it Turbo Lag?
Well, I am definitely guilty of shifiting up at rpm's lower than you use
(usually around 3k) and downshift around1.8 to 2k. This car is so easy
to just go sailing way past the speed limit, so I guess I'm just being
careful, and in doing that, I am ending up shifting just before the real fun
starts. Are you sure the turbo is fully spooled that low (1950k)? I
figured the push I described in the beginning post was the point where the
turbo is fully spooled. Maybe it is just the point where the gate fully
closes and gives all the boost.

<Much snippage>
http://tinyurl.com/33j42 shows a comparable power curve (IIRC, the TT225 has
a less peaky power curve than the 180, so the torque will be even lower) I'd
say that 3000rpm is basically just getting onto the torque curve (around
half of the rated power output of the engine..)
Quite a few rechips lower the point where the boost comes in (mine does the
opposite, which I prefer, in terms of engine response - it feels much more
like the 180 I originally test-drove. I know that this sounds odd, but a
sharper curve and higher peak power /feels/ sportier, if you're more used to
tuned normally-aspirated engines)

Re: Is it Turbo Lag?
I have doubts that the car has been chipped. As far as I know, the car was
a lease return and was registered in Connecticut. Why would somebody mod
their car when it is not really theirs does not make sense.
A friend of mine has a 99 A4 and he says that his turbo kicks in at around
4k. I don't know if that even merits comparison.
I am thinking that it is just a matter of me getting acclimated to the cars
abilities and limits. It is after all just a 4 cylinder engine and it's an
avant (heavier than the sedan). To expect super performance is not
realistic. Expecting good performance is more like it. I still love the
car.
Thanks for all the responses. There's a bunch of good people in this ng.
I appreciate it.

a lease return and was registered in Connecticut. Why would somebody mod
their car when it is not really theirs does not make sense.
A friend of mine has a 99 A4 and he says that his turbo kicks in at around
4k. I don't know if that even merits comparison.
I am thinking that it is just a matter of me getting acclimated to the cars
abilities and limits. It is after all just a 4 cylinder engine and it's an
avant (heavier than the sedan). To expect super performance is not
realistic. Expecting good performance is more like it. I still love the
