What are the long term fuel trim (LTFT) and short term fuel trim (STFT) at idle and under load.
What has been done to rule out clogged fuel injectors?

It's pulling fuel on long term an adding on short term an I ran some injector cleaner thru it along with some 110 octane

So did the injector cleaner make any difference?
Consider an injector cleaning and flow test service such as InjectorRX.com. Once cleaned and tested they are as good as new. Cheaper than new. Best part is the report that will give the flow rates of each injector before and after cleaning. I really suspect that this will tell you that there's a big flow difference between the injectors.
