You're vac is low as well. 13inHg is not a healthy motor. Do a comp/leak down test.
Good news though you're oil pressure is awesome at cold and warm.

thanks. What would be normal temperature for egt? Is there a number I should never go over such as 1500 degree F? During normal cruising/driving, it usually stays below 1200 degree F on highway (70~75mph). Please note that the egt probe is mounted right next to the turbo housing on dp. Should it reading a tard lower than if it was mounted on the manifold?
I did a little research, and -8.7 psi should be normal for stock sr. I've checked every piping and clamps. I found no leak anywhere. Timing was untouched. The car idle fine at 900rpm. Cold start would jump up to 2100rpm, but slowly down to 900rpm.
It does have a notchy idle jump every one mine from 800~900rpm for about 5 sec. I think this caused by air trapping in the coolant system though. It was worse before I bleed the coolant system.
Any thought welcome.
