Yeah when I started getting looks from morning runners in my suburb I decided it must be a lot louder than stock.....guess I naturally just boosted stereo volume

 

Moon it's going to be louder

 

Just recieved an answer from G Saab, the fella there said He has a SS HHR it was the test vehicle for this valve, His is tuned to 315 and 370, he has been running the spring it comes with.over 2 years , Guess we won't need the spring kit, unless you put a bigger turbo on.

 

Installed mine yesterday. Removing the plastic cover was a good idea although I only removed the left two and propped the plastic up and out of the way. Also removed harnessing as necessary. Found that a 1\4" drive 10mm socket with a 1" extension worked best. 3\8" drive was too big. Put a drop of Loctite on each screw and torqued back down when the Forge was in place. I also wiped the o-rings with high temp grease and made sure there was no particles in the grease before I installed it. Before I re-attached the vac hose I snugged the cap with a pair of Channel Lock pliers since there are no flat spots to put a wrench on (?).
As far as sound is concerned I'm not sure that it is much louder than stock but definitely a more robust part. I'm happy.

 

Hey Victory, what spring did you end up going with?

 

Yellow. So far so good but it's only been a day.

 

so if im on stock psi can i use that until i get trifecta tuned?

 

I've switched from green to yellow...and from yellow to green. I honestly can't tell a difference. Thats with the 24 psi GMS1 and my 27 psi Trifecta Tune..

Some people will see that they "hear less flutter"....but I honestly can't tell the difference..

 

but that on higher pressure, wont it hold in the pressure if the spring is meant for higher pressure and im not running higher pressure

 

Isn't green for up to 24psi? Yellow to 35psi?
