forge dv' s question

Installed a set of these and was wondering is it supposed to be louder than stock them seem quiet...I already have a dci...no check engine lights and car runs well but them seem very quiet if they weren't working I would get a chk engine correct?

Just to add I am using the yellow springs...is that overkill with map 3 on the jb3 2.0

do you have a boost gauge? thats the best way to tell if you are having issues with alot of things on your car. the yellows are what almost everyone uses, but i'm not sure about if they are too stiff for map 3, most guys are running map 5 or higher when they swap out the stock dv's for forge ones

Yeah boost gauge values looking ok partial throttle is like night and day much more responsive...my stock valves were damaged which is why I replaced them...but should I go down to the green springs

I just upgraded to forge DV w/stett charge pipe running green springs on GIAC stage 1 (soon to be stage 2). I don't notice any change in sound, but it might be hard to hear because my exhaust is upgraded as well.

General consensus is the yellow spring is good for any tuned application on this car.
