Is 11 in HG for a 3.33" low?
Forgive me guys but I'm a newbie at reading the gauge. I'm getting about 11 in HG Vacuum on the meter and I've got the 3.33" pulley. Is that correct or am I leaking somewhere? I managed to hook up the boost gauge but I put a kink in the clear plastic line that runs into the t-fitting on the vacuum hose. Should I replace that plastic line?

I had a leak for a long time.
Turned out that it was both the gauge leaking where it met the tubing, and a leak at the EGR tube at the back of the manifold.
I found it by going to a shop with a "SMOKE-IT" machine. They pump harmless white smoke through the system - wherever it comes out - there's your leak.
Took them all of 5 minutes to find it - I had been spraying brake cleaner over my vacuuml ines for months before that.
I now read 19-22Hg. It seems to vary a little by outside humidity and temp - it's usually at 19 however.
Now I'm still trying to figure out why I only read 7.5PSI of boost with a 3.12" Pulley.

I've always suspected that it could the tubing setup because it didn't feel that snug at the connections. I'll look for the copper tubing and try that out instead.

But in my case, the tube was fine, just the connector sucked.
