Hello all, me again.

Having some issues with my Cruze lately :

Throttle position is 94.9% at idle and engine load is reporting around 28% also at idle.

Turbo has a lot of trouble hitting 16 PSI and the max is 21 while also quite a severe power and fuel ecnomy loss.

Things I have to done to 'try' and remedy the problem :
DPF and Cat cleanse with hot pressure washer and high pressure air compressor
Brand new heavy duty diesel coolant
Brand new fuel filter, air filter and oil filter along with brand new oil.
Upper engine decarb cleaner into the throttle body
Cleaning MAP sensor (this is working fine at a 1:1 ratio)
Cleaned MAF sensor (haven't checked this value yet)

Things I need to :
Take off intake manifold and clean it (a lot of EGR and PCV contamination)

Also, does anyone know the purpose of having a second catalytic converter?

I got one in my downpipe and have a second one in conjunction with the DPF unit, this does not impress me.
