I have a question about the shims that go into the Forge 007 DV.
I believe they are supposed to help give finer tuned pressure.

I.E. You're car boosts from 10-20psi, and the spring in the DV is rated at 5-10, and the next spring size up is rated 20-25; you can add a shim or two to the first springs so that it may fit your individual turbo specs?

I haven't really found any descriptions about the DV except on how great it is. lol. So, any information would be great.



Thanks


P.S.
I have seen a few DIYs on DVs none of them really explain the shims. If I have missed one then please let me know.
