Recently bought stevieyids old ABY S2 Coupe (rs2 conversion) now running with a know working ECU with the Homefry N-stream (1.6bar) when i installed this the car was boosting to 1.6bar but never solidly held 1.6bar seemed to flutter on the guage around 1.6bar and now it does the same but at only 1.4/1.5bar, ive checked all the silicon boost hoses and everything seems to be tight, same ive checked all the vacume hoses and also all tight and in good shape.
Firstly any ideas where or what could cause this fluttering on the guage and not reaching max boost?
Secondly, could it be down to the PCV system? and if so id like to replace it all with a catch tank, i know this has been done and probably discussed to death but i cant seem to find a difinitive post with all the details/parts required to completly do away with the system.
If i was to put a breather filter on the camcover breather that normally vents back to the turbo inlet hose? and block the inlet hose up with an appropriate sized bung (is that ok, nessasary or pointless??)
Next, the breather at the back of the head (LHS) a silicon hose from there to a catchtank?
and finally, the metal outlet on the crank case a silicon hose from there to the catchtank?
what am i then left with that needs removing, or have i got this completly wrong?
