What spring and how many shims would u use with mods like CAI,DP,RP?

Blue spring and 1 or 2 shims. I had problems holding too much boost with yellow and two shims so I put the stock BPV back on. I was also tired of the ping noise all the time. Just monitor your boost levels at WOT and see if they stay around your target.

I'm running blue spring, one stock shim and one I made that's a bit thicker. Red was giving me surge and blue with stock shims wasn't holding for me.
