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

also i never trust the readings of vacuum on my boost controller, ive seen anywhere from -78 to -99 and every time i check my vac with a boost gauge its always right at 20hg warmed up.

before i did my manifold work (gasket + stud replacement + resurfacing) i got -98/99 every time, then i put it back and got low 90's, now im getting mid to high 80's, sometimes it goes to 96 or so again.. its so inconsistent.

yet every time i bring out the boost gauge i get a 20hg reading
