If you want to read up on all kinds of information about injectors you should go to their website and read their tech articles. You will then understand how your cheap injectors are never going to suit you even with a good ecu, and how your safc will not allow your ecu to calibrate to the correct dead times of your injectors.

I HIGHLY doubt that your wideband is bad, but your narrow band may very well be. Changing your narrow band isnt a bad idea but since your thinking you might go standalone later, you should just fix your other cars or whatever you say your going to do to them, and get good injectors and a standalone later (living with the poor idle in the mean time).

From what I have seen with deatchwerks, you should just be happy your car runs. Take it however you want to take it but I am being honest and helpful. You will spend more time and money trying to bandaid these junk injectors and bench tuned ecu/safc than what it would cost to do it right.

You so far have:
2 ~$500 ecus
2 sets of injectors

when starting out with injector dynamics injectors (or even some lower cost msd injectors would do much better than this) and nistune or aem you most likely would not have this issue to deal with, you would have better parts, and you most likely would be money ahead.
