I did prefer the Unleashed tune for a daily driver but it had similar issues when the engine is cold. I did a throttle reset and it seemed to correct for a bit but the adaptable learning seemed to make it come back.

I have found recently after I plugged my drill hole in my CAC as well as ran a couple tanks of premium the truck is running much better on the stock tune.

Might try a custom tune again some time soon but right now I am happy with no issues and the stock tune.

I have had no problems with 5 Star. I always run premium unless i'm on the ethanol tune. E-30 or E-50
