I had a Drag comp on my 00 and sold it to a buddy that has a 98. 5. It worked good for the first day then started cutting out, getting stuck on the levels, and a few times killed the truck. We installed it right, used a pump cover, checked everything we could think of. This never happened on my 00. I had the drag comp updated from edge right before i sold it. Anyone have a idea why this is happening. It should work fine with the years 98. 5 - 00.
