I have a 15 RAM 6.7L that smokes white and smells rich.
I have an MM3 tuner on it.
If you turn off the number, one injector smoke goes away.
I put a new injector in, but I still have the same problem.
Any ideas?

How many miles?
Have you scanned every injector to see if you have more than one bad?
Does it run differently power-wise, or does it hesitate to use the exhaust brake?

Another possibility is low compression on cylinder #1.
A quick and easy check for this would be to run a “Relative Compression Test” with a lab scope.

Yes scanned every injector.
100k miles.
The idle is rough.
That's next.
I would've done it but dropped the compression test tool.
I am getting a new one, but why would it lose compression on that cylinder?
Hard to say, could be a valve, rings, cylinder, head, or head gasket.
Please keep us posted on the compression test results.

But it doesn't over heat and does no blow by.
