Throwing Codes Again

[Fireman Crawler]

P0261 Inj Circ Low
P0263 Cont./Balance Fault
P0336 CPS Range Perf.
P0671 Glow Plug #1 Circ Fail

2005 F-350 SRW.
I've had the FICM repaired by the guy that does them on here. FICMRepair.com
All injectors have been replaced a little over a year ago. #1 glow plug was replaced then too. Head Studs have been installed and EGR has been deleted. I run the 4" Silverline Exhaust with a Superchip 1805 programmer. I drive less than 25 miles a day with no towing.

It isn't doing the crazy vibration like when the FICM went out. Some mornings I've noticed that it will idle up like normal then all of a sudden you hear a noise like the turbo is blowing out a burp and it will idle down. When this happens it will burp out a small amount of black smoke. Oil is rotella. It's got a new air filter.

What would be causing these codes. Could they all be true or think this could relate to my FICM again?

Sounds like a bad injector, you could check it like this.......Why you shouldn't drive around with injector codes!
I would chit can that tuner until you figure out the problem.
