DV spring
 

I got a Forge DV and im just wondering, what spring are you guys using, i just left the one it came with and im thinking about changing it out to the stronger one but i want some input, is it better with the weak one or the stronger spring?

I use the one it came with (green i think?). I also get a nice loud PSHHH sound when I let off the gas b/c of my airbox mod. As long as it isn't letting off boost too soon, you should be fine.

thats what i noticed, the stock one i could rev up to like 4500 and let go and ill get a clean Pshh sound and with the forge at 4500 i cant even hear it but down like at 2500 RPMs it will kick off with a clean sound, shouldnt it let out at a higher RPM?

RE: DV spring
 

hmm...in that case, it sounds like you might want to try the harder spring.

RE: DV spring
 

What do you guys recomend, what color spring? the hardest one or would it be best to see if the middle one works better

Valve Spring color coding

Green - 5-15 PSI

Yellow - 15-23 PSI

Blue - 23-30 PSI

Red - 30 + PSI

RE: DV spring
 

Are you talking about rev'ing it at idle? And how do you have the valve oriented, which side is seeing boost?
