ManiN54... question for you.... in your opinion what's the best way to correct the lean condition due to ctls **'s? The old plugs are showing a lean condition (tan in color/no oil) and I've yet to find a definitive answer on how to correct the o2 sensor readings. No mil light but when I read codes with jb4 it always comes back with a "ctls ** detected" code.
Tan in color does not determine a lean condition, if it is tan in color and otherwise clean - no carbon buildup, it is normal. As for the codes you are getting; you will not avoid that if you are ********* unless you have the proper backend flash. Note that these setting are designed for off-road/track only vehicles.

As Dave requested; post up some logs and you can be further guided in the right direction.
Food for thought; always go for index 11 or 12 when buying new injectors. Also make sure your plugs are gapped correctly. 0.022” in your case.
