1994-2002 2nd Gen Cummins Towmax Combo Kit 450hp

Mack is the man to deal with! Good product noticeable power gain along with lower EGT.

Only half of my order showed up. Mdc customer support was supposed to call me and give me an update but never did. I still don't have the injectors I paid for and no answer on when they will get here. This is for my work truck which is costing me money everyday it's down. Waiting for over a week on the rest of my order is beyond unacceptable
