Hi Rawze,thanks again.
I am listening, learning,taking advises as I admit,that I am not experienced, and have no knowledge as you do...
That's why I am here..talking to hard working guys,as I am and appreciate being here
No,no and no to all your row of first questions...my truck since I never been at cummins or updated...
Sounds dummy, I thought that no updates on that age engines,and imagined that sofwr and hardw.is factory spec.
I have new Ecm received today...and will bring to cummins next week...they asked old ecm as well to transfer parameters from it...
Your advise,what to ask them to do,to not mess up with new unit?transfer parameters, programing,calibration and updates?
We test CAC last year,was no leaks,I have 5 inch exhaust piping and mufler replaced last year as well.
But you could be right about boost...but boost depends on fuel supply and performance?
I had 1 time oil leak on hot side of turbo ,when was really cold 1.5 Mont ago....wind chill feeling-40 c...fuel been freezing and engine ran on few cylinders...
No smoke,no leaks,no oil consumption after that...
Do I need to think about turbo replacement?
Another question about cylinder test
I have
cylinder 105
2nd-107
3rd-90
4th-93
5th-102
6th-102
Front bank 100,rear 98
This at 655 rpm.

2nd-99
3rd-84
4th-83
5th-119
6th-117
Front 93,rear 105 at 848 rpm.
What does it say?
Crack insite,and chinese inline adapter is safe to use?
