I've noticed that when I let off the gas in my b16 that my boost/vacuum gauge goes to 60cmhg (metric gauge). I have a feeling it may be time to re-ring this winter as it's been boosted for 2 years. It's a built b16, Weisco Pistons, Eagle Rods, Darton Sleeves.

Thanks!

60cm hg is equal to about 23-24 inch on my Autometer which isn't too far off from normal. Mine pulls 20-21 on decel. That usually indicates a strong motor I thought. Maybe someone else can chime in and tell you to go ahead and boost the hell out of it the way it is.

depepnding on overlap, but yeah that sounds about normal to me.

Ok well I guess it's time to see what over 14lbs feels like.

high vac on decel is normally cause you removed the PCV setup; that controlled vacuum leak that's engineered in

Perfectly normal.

How much boost does your map sensor read? Use it, lol. Yea I see 26" with pcv system removed.

might crank it up a bit more tomorrow night and run your del slow

I have a 3bar so I think it will work.

my all motor setup use to pull close to 29IN-HG on decel. perfectly normal. U usually have a problem with the motor if your vacuum at idle is low (say below 19 In-Hg)
