I got tired of having the boost gauge temporaily installed (hanging on rubber bands) and did something about it. I put it in the cluster between the speedo and tach. Seems like an ideal spot.
I checked the over boost relief valve and it leaks when pressure tested (no power to solenoid). I connected power to it, it drew 1/2 amp but I did not hear it click. So I bypassed the solenoid and still can't get it higher than 9 psi boost.
How easy (or hard) is it to reach 12 psi? The FSM says 12 psi at full load at 4000 rpm in first gear. I was in testing it while going up a hill in 4th and flooring the pedal. Is it possible 9 psi is normal for the way I was testing it? My transmission cannot be put into 1st.
