Forge -DV- Tune Up Springs
OK.
What am I looking for with these different springs?
I am chipped, and currently running the Yellow spring. Car is running good, but I want to try the Blue spring, but am not certain what to look for. I don't want to overload this tiny turbo.
How can I tell if the valve is dumping properly? Am I understanding correctly, if the spring is correct, I will maintain constant, greater boost longer?

You already have in the correct spring. You want the weakest spring that will hold the boost you run. Basically you are looking for is a clean release at peak boost and your not releasing boost early. If you think you need more tension, use a shim

So now that I have a Boost Baseline with the Yellow spring, if I try a washer/shim and my boost pressure increases, and doesn't fall off, should I keep the shim in?
here's a run down
green spring = stock psi
yellow spring = chipped/diode mod
blue spring = BT ( ~21psi - 29psi)
red spring = B MFing T (~30psi +)
though i sold my Forge 007 DV, and started using the 710N... i could honestly say the 710N feels and performs slightly better. also the "blow-off" sound (re-diverting of the air) is louder~

^ i got the 710N from my friend who's a tech from Audi. he says they came out with a revised ver., the new 710NC or something that can deal with higher compression/psi.
hey for $40, not bad
btw, when u had it over the charge pipe, howd that work? with all the piping and such
