Did not see anything out of the oridinary when comes to boost? It the hose was cracked to the point of allow a leak, it seems a considerable drop in boost would have been seen on the gauge
I just replaced both the lines on my car, I am at 120K and both were all dried out and cracking. I measured the stock line and bought 3/16" ID line at napa and used it for both. I had to work with the guy to find one with thicker walls so it wouldn't collapse in.
Only pain was trying to get the new line on the fittings, especially the tight bend one.

Rough idle/lack of power and hissing when you step on the gas? Do you step on the gas more and more only to barely accelerate? If so, check your vacuum lines. Mine was shot between the s/c and the bypass actuator. I replaced it and now it's like driving a brand new car.
Just thought id let you know. I spent years trying to figure this out and always thought the vacuum lines were ok.

Found another crappy vacuum line - the big hose w/ the clamp that is by the TB. The crimp-style clamp must've worn out over time and lost it's tension. I replaced it with the screw-type hose clamp and no more leak there.
The car runs like a RAPED APE now and gained 1mpg. Just thought i'd update.

When cleaning the TB do u guys spray the tb (when its off the car of course) or do u just get a rag and spray tb cleaner on it , and then scrub with it? Only thing I know is that u have to use non-chlorinated cleaner.
