I really appreciate the input! Actually that makes total sense, i dont currently have a BOV.... it just pushes back through the blades and makes cool noises! Wow... i think thats 100% whats going on actually... cause when its surging its making all kinds of flutter noises, building boost at idle, then not! it would fuck everything up! Soooo is my best bet to add a BOV? or could i switch the maf too the turbo inlet?
