Well I just installed my boost gauge, got it electrical taped to my dash until I can get a a-pillar. It idles at 15 vac, and when i'm driving and decelerating its at 20 vac. under WOT it goes up to about 9 or 10 psi. This seem normal for a stock car w/ RS bov.
 
yea the boost seems normal, when i installed my gauge i got about 10 then i did the BCS mod and got 12 so thats what im sittin at right now
 
ya mine is at 10 at idle, 15 on deccelaration, and 11-12 under WOT, i got k&n intake filter, intake pipe, and bcs mod. :thumb:
 
There should be a write up of it in the tech section but i'll do my best to explain it to you.

The BCS has two nipples that two hose's are attached too, one of them has a piece in there that blocks airflow. so what you can do is take a drill and drill it out be veryy careful when you do this its easy to crack these things. once you have it drilled out you will gain 1 or 2 pounds of boost. Its really easy but you only gain 1 or 2 pounds
 
Where did you run the vaccuum line for the gauge?

Where did you tie in your 12V source?

Which A-pillar pod did you get?

Did you zip-tie your vaccuum line out of harm's way?

Just curious...I'm in the middle of that (dropped a broken zip tie into my motor in the process...don't ask).
 
Its just a temp install to have the gauge in ### i got tired of looking at it on my desk. Havn't hooked up the 12v yet ### its like a 6 inch wire, no a-pillar yet, and havn't zip-tied the vacuum

10 inVac at idle seems to low, expecially for a stock cammed car. The norm is usually 18-20 " at idle and 22-24 under deceleration. This will vary slightly depending on your elevation above sea level.
 
I run the exact same numbers you do with my boost gauge. Look on cold nights to see if it boosts higher. I have hit between 12-14 on real cold nights. In all it is completly normal for a stock car. Reminder don't sit there trying to compare your boost gauge reading to your OEM boost guage reading. The OEM one is often inaccurate
