I'm only getting 1.7 bar indicated on the dash gauge. I have checked
for leaks, replaced bypass valve and WGFV, I even tried blocking the
hose to the wastegate, but then I only got 1.6.. I tried using
regulated, pressurized air on the small line to the ECU, I adjusted it
to about 2 bar absolute pressure, the dash gauge shows 1.9 max. With
the standard pressure transducer should this be correct, right?
But I still wonder why it doesn't give full boost, even with the lower
wastegate hose blocked off.. When I did this on my old 200q10v, it hit
the overboost cutoff very quick..
I removed the top cap on the wastegate, everything looked normal in
I tried pulling codes, nothing.. (4444)
Any good tips? I'm really puzzled..
