Ok, another update to bring all the info together.
DPF gutted and mapped out.
Fuel pressure regulator replaced.
MAF Replaced.
AIT sensor replaced.
EGR Blocked off and disconnected.
Tuning box discovered and removed.
Aerosol EGR cleaner used (very little smoke during or with full acceleration bursts).
Airbox and filter both clean.
Tried combinations of:
Air Filter removed.
Filter and MAF in place upside down in order to rule out blockage on air intake.
Air intake with MAF plugged in but removed from hose.
Smoked on all of those combinations.
Now left with little options but to look at fuel issues.
I was going to attempt a leak off test, but the daisy chain leak off pipes are awkward to get to and very tight, and I fear I may not be able to reconnect them once this has been done.
I have tried searching for guides or videos on this engine but found nothing.
Fuel filter is a DIY option, but I need to borrow the tools to do it (I know someone).
