Just wondering what you guys see on your boost gauge on the vacuum side, i have -18, does it sound right?
I can also boost up to 21 psi without any sort of boost control (HKS EVC 6 EBC turned off and stock boost solenoids disconected.)
My mod list is:

Forge WGA
HKS EVC 6 EBC
ETS Intake
ETS 4" IC
ETS LICP & UICP
ETS 3" Turbo back exhaust

 

21 psi is the forge doing its job.... on the stock wgs you might see 13 to 14psi

and vac is about right... 18 to 15

 

looks about right to me.....

 

Stock I have 18inHg and 15psi. I double checked with my modis and my numbers are pretty much the same (my boost guage can't really display less than 1inHg/psi differences)

 

When I start the car and it warms up I have vacuum at 18 but after driving for a bit it will drop to as low as 20 is this right?

 

For the vacuum i think the highest the best .... as for boost
So if between -15 and -18 is ok then i'm happy. Thank you guys.

 

Ive seen mine as low as -22, but the gauge could be off.

 

Mine also drops to 22inHg every time I leave it in gear and decel.

 

mine is around 21-22inHg at idle... drops to about 24inHg on decel...

 

I checked mine last night. Im the same as u

 

probably because of the same gauge... I have the prosport premium

 

15psi? Do you have a boost leak or something? stock is 21psi.


Mine is 20inhg for idle and i hit about 24psi

 

Maybe mine wasn't made on a Wednesday.

 

I think he meant 18-15inhg?
