To the OP;
I think you're gonna end up at a dead end with this thread. Those of us that purchase these trucks usually don't try to cut corners on parts. Sure we don't always use OEM, and in some cases prefer not to because there are plenty of reputable aftermarket vendors that are equivalent, but this is one area you should NOT cut corners.
If the engine is the heart of your truck, the fuel you put through it is the blood. If I need to go further with this analogy, then a Cummins may not be right for you.
This is absolutely the area you want either OEM or a PROVEN injector vendor. There is absolutely a load of information on this subject. I have not yet needed to go down this path but I am fully aware of my options when it's time and plan on going with BBI. Maybe other companies can come around and provide the quality they have set a standard with, maybe not. As well, I'm not associated in any way with them, but I have done my research regarding this type of thing.
@seafish is absolutely correct in the post. This is easily a 10k engine if not more. WHY on earth would you gamble on this?
Save 2k, you get a warm fuzzy feeling for a handful of miles, until an injector fails, you neglect it, and you melt some pistons. Now you are in for a new engine or a complete rebuild.
I understand the want to save money and that this thread is for those that may have experience with what you are looking for, but I highly doubt that you are going to find anyone that has dared to run these things. If they are, they don't know much about the fuel systems on these trucks and the huge role they play in the health of of the engine.
Are we trying to sway your decision? Sure. But in the end you gotta do what you gotta do. But if you decide to try these things, it's on you. As well, if you do, post up in a year after you get em and let everyone know how they work. If they are still doing good, you lucked out. If not, own up.
There are lots of Chinese parts that say Cummins on the box. Look at all the crank seals out there. $14 "OEM" seals. It happens a lot. Patents and what not do not apply and they can usually get away with changing the logo ever so slightly that the common eye cannot catch. I've seen it a ton in the MTB industry.
The warning has been set forth, proceed how you want. Maybe someone will chime in that's dared to run them as well.
