did they give you that damn 500/1650 ecm tune because they are not worth a damn.The best luck I have had with my isx have been with a 450/1850 then with a 535/1850 and my last one is a 475/1850. But as cummins is allways changing there tunes it can be hard to find a tune u like. U also have the option of deleting all that crap and starting fresh. But as art stated your truck is sick if it is sluggish.
