My compressor is surging. How can I find out what is making it do it? I had another thread on here and you guys said I was maxxing my turbo out at 27 psi, so I turned it down. It stopped for a while but now it is doing it at 23 psi. I put an old greddy bov on it, and pressure tested my boost system from the turbo inlet to the end of the intercooler piping, and fixed lots of leaks. What can I try next? Can my mbc make it surge?
