Few issues Options

[Defgeph]

From the begining of my swap I've had low vac issues. I replaced hoses tightened everything up capped off holes.

I eliminated my AC and power steering. I have the hose for the AC idle up capped. Would I be better off capping the two PS vac lines?(current setup) Or should I connect them to each other with a hose. I'm close to having full vac, but its still alittle off.

Second thing, when I slow down and put the car into neutral the RMP's dip way below normal idle. After running at like say 650-750 rpm for a few seconds, it raises back to 1000 where its been since the begining of this project. Sometimes the car stalls, I looking for some suggestions or ideas.

I've checked timing, its set at 10d's.


Thanks guys

Brian, whats the brand name of this inconsistent boost controller ?

its a greddy profec II spec B

my experience has led me to believe that the -XX vac reading means pretty much nothing, as it changes so much, and my friend with the same controller gets the same inconsistency

your not always going to get exactly the same vac. everything from engine temp, outside temp, and rpm can result in slightly different readings. what you have to do is figure out how to convert the -99 to a normal vac reading. youll probably find that the difference is something along the lines of 20.0 -20.9 vac.
