Help with Idle MS3X

Yeah it's very down on power and removing timing did not change anything. Any recommendations on how I should test for a non firing cylinder(s)? I watched one video where after running the engine for a minute you spray water on the headers and check for abnormalities in the vaporization on different cylinders. At idle it runs pretty smoothly, rich (10.5 AFR) but overall ok. Running rich could possibly be because of unburnt fuel but that's just a guess.

Ah I see SpartanSV, that complicates this a bit more! I pulled the spark plugs and did an Output Test Mode - INJ/SPK on Coil A and then B, both batches spark fine.
Braineack how do I do an output test mode to lean it out? Am I running the engine, disabling cylinders and seeing if it affects anything? If so is that that INJ/SPK Disabling test mode?

Oh damn that is pretty rich! I was so preocuppied about "leaning out" and damaging my engine that I stopped tuning the idle once it stopped stalling and oscillating. I just fine tuned my idle VE table so it's much better now at a pretty steady 14.1-14.9.
So how should I go about testing injectors?

I have been comparing the base tune I'm using from Trubokitty to the DIYAutotune's 01-05 MS3PNP base tune. The injector timing is pretty different, any reason for this?
