Hey guys...haven't been on here in years. Sadly, I have to sell my baby. 2002 turbo'd P5. Here's a link to the craigslist ad, which has a list of all the modifications:

It's a great car and is super fun to drive. Tell your friends...
if you're still looking, i have had the clutchaster stage 3 for quite a while with around 200 at the wheels. no problems whatsoever...just a little squeeky at pick-up when it's cold. i got it from www.rr-racing.com
dude, it depends so much on weather, driving style, supporting mods, etc, etc, that there is no 'magic' number. if you don't want to blow your engine and you want to leave it stock, don't adjust the boost!
