Installed the tap chip friday evening, but was getting to late to put the 
spring in.
Drove the car to pick some things up less spring, not much of a change worth 
talking about. 
Up bright and early Sat. to install the spring, weather was a little nippy 
here in the DC area, and after the drive last nite I was thinking the spring 
was a waste of time. So in goes the spring, the 20V really has advanced in 
design compaired to the 10V and much easier to work on.  Told the wife I will 
be back in a minute, just going to try it out.  Well that was the fastest 
hour of fun I have had since I chipped my 86tq two years ago. Car ran 
fantastic, except it thru the air comp.   belt, I think it's the AutoZone 
K.Springfields just do not like running the 7000 rpm range, sure glad this 
rascal cuts out @7200 rpm, it's for sure there for a reason.
Now for some info from all BTDT's.
I have noticed an increase in motor vibration after the timing belt job.
Used Blau. parts and tools, harmonic balancer is straight, tensioner is 
seated and all looks good. I am cocearned it may have something to do with 
the dist. and the crushing off of the old rotor, could this cause a vibe?
I will change all the belts with another brand, just in case.
Also, the car was running so good Sat. that on Sun. decided to install the 
cone K&N air filter that I had ordered with the chip. I know, no flames 
I should have washed the engine and compartment down first because when you 
get into boost this thing sounds like it could inhale leaves from ten feet 
wow, what a sound, cannot say if there is a performance diff. but the sound 
sure makes it feel faster.  But now I am also hearing another sound when the 
boost starts coming up?

A metalic spinning that whirrs up and down with the turbo.
No, must be a cat shield, no it's the turbo.
Pulled the intake hose from the turbo. looks great, no metal shavings, spins 
No movement front to back, slight from side to side, I have felt worse.
Any thing else to check before pulling the turbo?
