Is the adjustment for the replacement injector being done correctly?

First, I would hope that you have a warranty on the injector. Next, I would have placed an old injector on number 6 after the second one failed.

Lastly, is the truck deleted or stock from factory with DPF etc. still functioning?

What does the tip look like and the top of the piston look like after one fails? Some pics would help.

Has anyone bothered to do an injector leak test on it to see if there are leaky injectors?

What does your DPF history look like?

Using any coolant or oil?

Everything is stock. I change oil every 10k miles. Half a gallon oil use every 10 k. 2637 fc is there when i check for codes. 1117 fc for ecm data erratic is 90% of the time there with 2637.
