Does it accelerate well or seem way down on power? Where did you tap into for the boost gauge? Check out http://public.fotki.com/ttschwing/bo...u/boost_gauge/
on Ttschwing's page to see where to tap into.

Default this is where i hooked it up

this is where i hooked it up and now that i fixed a little crimp in the line, my boost seems right , just backwards?
at wot,the needle goes clockwise to just before 10psi(like 9 psi)and wen i take my foot off the gas, the needle goes counter clockwise just past 20psi(gets to about 21)

red is normal driving
blue is idle
yellow is decel in gear
green is wot(wide open throttle)

any opinions?

Thats exactly right. The left of 0 is VACUUM and the right of the 0 is BOOST. When you aren't in boost you are in vacuum. You will most doubtedly run more vacuum than boost on one of these motors.
