Ok runnin a 535 isx cm871 with egr in 2006 kw. On this paticular set up they have 4" exhaust off the turbo for about 18" and have the intake tube between the intercooler and manifold. My question is has anyone opened up these restrictions and if so what effects did you notice? Currently running with egr unplugged and not worried about that, just don't want to affect turbo performance or cause a possible problem there(have already replaced it once because the vv actuator was frozen and really hurt engine brake performance).
