Okay this is where I'm at with this thing. I did a stock SR swap and hooked up this Greddy Profec B and the only thing that I have done is changed the reading from kPa to PSI. When I crank up the car it reads -86 to -89. What am I looking at because for some reason the instructions just aren't doing it for me. A negative 8.6 psi...huh?

i hope not -8.1psi cause then you got a massive vaccume leak and your car wouldnt even run lol. normal vacuum for a SR is -20-22psi, not sure what it reading at, my boost controller i cant change it, it reads boost in Bar and vacuum in millimeters of mercury mmHg yea weird lol

my boost gauge on my blitz turbo timer reads -.73 sometimes -.80 kpa at idle.


i'm not even familiar with a boost gauge that reads in psi. i'm so jdm

Well the boost gauge at idle reads -20 on the vaccuum side and the boost controller reads -86 to -89. I haven't looked at the boost controller while driving to see what it says but the boost gauge goes from -20 vac to a little over 1psi when the bov goes off.

hey bro get online and down load the manual for it. it will explain it all. i got on and mine works great
