So, i have the forge WGA and the 5-10psi spring (green). And it'll hold boost until WOT, and just really low boost after. Weak spring, or upgrade spring? any ideas?
I had a Forge motorsports dual piston blow off valve on my 2003 mazdaspeed protege along with the weapons r cold air intake.. It makes the fluttering noise when i release the gas while in the range of my turbo. I took the blow off valve off and put the stock one back on thinking that would fix...

Let me get some opinions!!!
Yes, I know it doesn't increase performance, but damn we all love that blow off sound. I just don't want it to affect the turbo or engine in any way differently than the stock BPV.
