100k mile fixes
Do not listen to the guy who says to replace the timing chain. These timing chains have no recommended interval and are known to go well past 200k miles on ECOTEC's.
I would do what people suggest.
Flush brake fluid
Flush Trans fluid
Flush coolant at or around 100k
New fuel filter
Clean MAF
Clean Throttle Body
Clean or replace air filter
New Cabin Filter
Replace any worn out suspension parts
If timing chain tensioner is noisy replace if need be

Some of that may be "normal" blower noise. Remember, the M62 and other roots series blowers are zero clearance blowers, the rotors actually do touch the housings, so a little noise will always be there. The couplers usually make noise less often than the timing chain tensioner. I'd replace the tensioner with the newer design if you are getting that kinda noise.
Good point Joe, if the blower is that noisy, the coupler could be going. Mine is getting loud, but I haven't bothered to change it yet. Can't hurt to put that on the "If your car makes this noise...replace this" list.
