at low speeds and part throttle i get a hesitation like a very quick misfire so the car acts like its tugging back and forth then it goes away i don't know if that explains it at all?

It could be a number of things.
Dirty fuel filter since your on e85
Plugs,cops,Iacv dirty or possible tune issue. I hear some shops don't get them right.
Where was it tuned?

I had brought the issue to my tuner which is shaun at aed and he looked over the tune and the data logs said everything is okay then he advise me to change the spark plugs and gap which i did i am running ngk 7ix gapped at .30 and the issue is still there. i dont want to replace anything i dont have too but from my research i had come to a possible conclusion that it might be the cops but i have no idea.

The cops can be tested so yout not out money replacing something that isn't broke.
That's what I would do. You can always pull one while it's running. If the engine doesn't change its most likely not doing its job firing that particular cylinder.
