has anyone noticed in the 2.4t (lpt) that there really isn't a difference between about 3/4 throttle and full throttle? My gf's dad's c70 is like that as well (its also a lpt). Is it because it's a lpt that for some reason w/ the programming that it's getting full boost already at 3/4 throttle. I kid you not, my car is not any faster floored or not.

Still quick though :)

The difference is the gradual pressure vs. the verticle to floored motion. The transmission has a "kickdown" option which normally kicks down a gear for passing. This usually does not happen if gradual pressure is applied. Try turning the wastegate too, the turbo will come in sooner.

I have a 850 GLT Low-Pressure Turbo. It is very close to (if not the same as) your engine. I also have noticed this only when punching the gas, as opposed to slowly accelerating. For instance, if I punch it 3/4 it will zoom the same as pedal to metal, but if I slowly increase foot pressure, it can definitely feel more and more acceleration between 3/4 and 4/4.

the S60 and all '99 and up bricks (except the x40s) have an ETM or electronic throttle module, there's no throttle cable. Under certain conditions, when the pedal in 3/4 down the T-Plate may actually be wide open. This allows the compressor to spool up on it's own without having to blip the throttle. It allows people who aren't used to driving a turbo to get maximum performance without having to play with the throttle.

yep, see now you guys are saying what I'm talking about. I mean, if I'm already in it 3/4 throttle, it just doesn't have anything left for that last push, like its already there. Gradual throttle builds, but this doesn't. Kind of annoying, I'm used to my firebird still I guess (and mom's Slk 320 benz).

Thats pretty much what I figured, either it was A: Out of boost or B: already at WOT
