so I have an 03 with a ported blower,tb,plem. with a 2.82 pulley. I thought I should have 15 lbs of boost. On my buddys autometer it showed 14.5 now I have my autometer gauge on it... it shows 11 ish. What should I have for psi? I did put mine in a dif. spot. Could that be it? or do you think my gauge is messed up?
Thanks guys...

is it a vacuum/boost gauge?
if so, what does vacuum read at idle, and what does the gauge read when the car is off.2005 v6 redfire mustang. yup its slow.

Where its pulling the source from is also very important, if you have it in a diff spot then yes it would likely read lower/higher.

with my pully combo i am suppose to have 14, but do to this wonderful thing called belt slip, i only run about 11.5. i can't wait to get a billetflow non-slip pulley. oh, and my automemter guage agrees with the dyno that 11.5 is all i am getting.

are you sure? i did not think i had any, but after watching the boost pres. and seein the dyno graph, i knew i had some. but was not worried, since my 450rwhp with a 2.80 and an unported eaton has been rather enjoyable. just decided that i would get the billet flow when i got my ported blower. which i will have soon. 500 here we come!

Trust me the belt could still be slipping. My procharger had a belt that was an absolute BITCH to put on and I had some pretty badass slippage.
Also remember its summer, their is less air to go around so you aren't going to be reading the same boost at 110* vs 75*2012 Race Red GT w/ a 5 Liter and a 6 speed
2010 Dodge Challenger R/T traded in.
'03 DBS Cobra .... Traded in, THANK GOD
'01 Ford Lightning.... Sold, sorely missed
