The waste gate on my turbo opens between 10 and 11 psi (assuming that my boost gauge is accurate, of course -- it's a brand-new VDO 0-15 psi unit, attached to a spare hole in the intake manifold). Is there any way of adjusting the waste gate to open at the "stock setting of 13 psi?" I can't seen anything on the waste gate that looks adjustable.
