Forge DV: Which color spring are you using?

Just got a 1G Forge DV for my Buschur upper IC pipe. What color springs are everyone using in them for pump gas boost levels 20-22 psi?

In order of spring rate (softest first), they go green, yellow, blue and red.

So far I've only tried the blue spring and it seems to work well. Just curious what others have had success with.

I've got the yellow installed currently. I will admit I've not really put it through its paces yet to determine if it's spring rate is sufficent for 20-22psi. It is what Buschur suggested I run w/ a GT30R setup (BR500BB).

I am using the yellow with no spacers currently. I may add one spacer.

I have the blue spring on my Forge recirculating bov and it works very well... especially after the reflash. I still get that half throttle "surging" at high boost, but Mike@Forge told me it's normal and it's actually working ok. As far as idle problems... none at all. I'm boosting around 20-21psi. Holds very well.

I'm surprised by that. Dave Buschur posted before (I think on his own forum) that he had the best luck with the red in his RS.

Red spring for recirc type. Perfect w/ no surge or studdering.

Blue was leaking for me.

Interesting... It wasn't but a week and a half ago I was told that.

Either way, I'll find what works best with my franenstien of a setup. I was just looking for a good starting place.

I wonder if this might be a difference between what works in a VTA vs. DV? I don't know whether Buschur had a VTA Forge on his RS since it is speed density now.

I used the blue with one shim for 22-23lbs and was perfect after switching springs and shims left and right. I have one for sale if anyone wants with all springs and shims (selfless plug)

True... Another question would be.. How much time if any, was spent with the car at part throttle under boost (during Dave's testing on the RS)?

My car will be back on the road this week.. I'll be able to do some testing then.
