    Describe the issue

    Bought a 2006 Dodge with 5.9 Cummins with 92,0000 miles. Performance was very good at time of purchase. After 2 tanks of fuel using AMSOIL Injector cleaner and Cetane boost, performance increased. Injectors must have had a degree of contamination blocking the nozzles. Much better now.
