I'm Leakin?

**quat** · 06-11-2008 11:34 PM

Ok, normal vacuum is 19 -21 in/Hg, I'm getting 10-12 95% of th time, and occasionally get a normal reading. My boost spikes at 12psi and holds at 10. (stock program) Can I have a vacuum leak without having a boost leak? and where could that happen?

Air conditioning, electric stuff, etc, could all contribute to low vacuum.

Do you have audio or anything stressing your alternator out?

nope even with everything shut off I gat 10 in/Hg of vacuum. Any other ideas?

Check all your connections, check valves, suction jet pump, check your vacuum lines for worn spots...GL

bumpo we need to figure this out!

well I've checked all my tubes and nothing seems worn, the only thing is that my coolant flange is leaking. but I don't think that would have anything to do with vacuum.

checked your DV?

**quat** · 06-14-2008 12:33 PM

**AudiA4Turbo22** · 06-14-2008 12:53 PM

huge bump...

What are the stock readings for vacuum and boost?

Im getting 15inHg and at idle, spiking 14lbs and holding 10lbs.

Should i be hitting higher?
