anybody have any datapoints on K03 turbos wearing out on cars running higher boost levels - ie chipped?  What kind of mileage - wear signs...?

My turbo _seems_ to spool up slower than it used to.  (next time I go out I'll put the car in 3rd, keep revs at about 1800 and floor it and see where the thrust really kicks in - I don't have a boost gauge so can't document that....)  I've got 88k mi on the car now and have had the car chipped since 20k mi. (MTM 210 w/ Supersprint exhaust)  I also live in Denver which is a little harder on turbos...
