22 psi - yellow or green spring

Mods are listed in my sig, have a tune now though. HP Tuned on 22 psi. Was wondering if I should stick with the green spring or go to the yellow. Want to up to 26 psi after meth. Need everyone's input, thanks

Should be fine with green. Is easy to try the yellow and switch back if you get a CEL or turbo flutter.

I should add that I'm on the yellow myself at around 23psi. It seemed to work just fine so I never bothered to put the green back in. Can hear occasional flutter when I run without airbox lid but no CEL.

the only mod's i have are the GM tune upgrade & the magnaflow catback exhaust. i installed the forge valve w/ the yellow spring & now the "check engine" comes on after hard accel while already moving - 2nd or 3rd gear. does anyone have a green spring they want to get rid off?

Didn't your forge valve come with both the yellow and green spring?

I used to use the yellow spring...but I think that the Green is a "safer" choice. It has been stated that others are using green on 20-25 psi with no problems holding pressure. Turbo flutter=not good
