With all my new mods, I have developed a fluttering sound at WOT.
I am thinking my Forge came with a 15psi max spring and that is the fluttering sound, that I am exceeding that boost and the flutter is the BPV. By ear, the location is high drivers side front which is the right location.
Only other thing I can think of is the wastegate. Anyone else experience this?
I figure throwing a beefier spring in the Forge is a cheap way of diagnosing.
