I'm getting -15 on the autometer and -5.5 on the greddy boost gauge / turbo timer.

I know they are reading different but I was just curious is this vaccume okay on a stock reman (non ported)?? I have an open exaust all the way except for the highflow cat.

Also my other question is, how will a car thats running very rich impair the vaccume at idle, the car has not yet been tuned so I'm just wondering if I'm having ay compression issues. I've done afew small pulls at 10psi just to feel the turbos kick in but nothing strenuous on the engine.

 

i get -20 at 700rpm, untuned

 

what is your setup??? And what can be the cause of a vaccume leak if I have no lines disconnected???

 

Warn gasket, UIM not properly seated, engine has low compression, double check everything. If the car is runnig rough at idle this will affect your readings.
15-18 is still ok. sometimes i get -16-18 if the car is idling like crap. (
