Vacuum leak? I've always believed that boost pressure would be affected by a vacuum leak. The guage remains at zero, yet there doesn't seem to be any <i>obvious</i> lack of power. Additionally, the "check engine" light illuminated at start-up and stayed lit for a couple of minutes.

I replaced all hoses with Samco units fastened with constant-torque clamps and replaced the stock BPV with a Hyperboost several weeks ago... but still, that shouldn't have anything to do with my boost guage not functioning. Could this be a slight vacuum leak? I searched the forum archives, but virtually everything I found suggested that I would also be experiencing power loss... which doesn't seem to have occured in my case. I mean, I suppose with 280HP you could lose 10 or 15HP and not notice, &lt;b&gt;if&lt;/i&gt; you're not always mashing the throttle, which I rarely do.

If you';re getting full boost and gauge reads "0", then boost gauge line fell off somewhere!

..and check the opposite end this weekend, when I have more free time.

Would this leak have caused the "check engine" light to illuminate?

Possible is it came off in engine bay somewhere, but unlikely.

If I had more free time, I'd tackle the problem immediately..

Ah, the pitfalls of working full-time while going to school full-time.

Thanks again!

In the mean time, you have a boost leak. Think about looking sooner.
