Bought a stock cam MDS delete kit from AMS racing. Truck runs fine above 3k but stumbles and dies less than that. Run just like vacuum leak. used starting fluid w/no results. Not many vacuum lines to screw up. Do I need to tune after a stock rebuild. Yea I got the mds codes but no others. Any help would be greatly appreciated. Thanklz Larry B
