What is you average PSI with these type/similiar mods:
I am (Just got new Boost guage and was surprized at peak boost)
The highest boost I am seeing is 13 psi with 2.76 (BF N/S) full idlers, 74.5: Belt, intake, catted x, CB, and Boost bypass. ISnt this low?

you should see closer to 14-15. I bet you have some belt slip.
not possible
Full BF idlers (4) and a belt so tight that the first time I put it on, it broke my breaker bar.
What else could it be that is making me have low boost?

I'm seeing 12-13 with a ported blower and a 2.93 and stock lower.
With that low of boost on a ported blower? Understandable for less boost with a 2.93, are you hp and tq numbers good?

People are too caught up with boost numbers. Lots of factors affect boost, including temperature, air density, altitude, corrected altitude, exhaust backpressure, and many others.

I am only seeing 11, maybe 11.5 with 2.93 and 4 idlers. :nonono: I think I am getting belt slip up top, but that is the tightest belt I can fit on the thing. Was hopeing to see around 13psi. :shrug: Maybe because of this hot weather I am loseing a bit of boost. Car was tuned when it was 10 degrees out. :uh oh: Edit: had the car out yesterday and had 12psi when I went from 6th gear to 3rd on a highway pull. :rockon: I'm gettin' there.

I see 14 with my 2.76 and 1 idler. Also who says the gauge is dead nuts accurate? Ive seen cars with the same setup as me showing between 13-16psi.
