Get a reflash and it will cure all your problems and make you feel like you have a new truck, well I know you have a new truck, but you know what I mean.
I had the smae problem and it cured me.

the reflash may not correct the problem. it may have injector problems, contaminated fuel, the reflash has not been correcting the injector issues.
