| Dont know where your from. But If your close to IN I would contact Jim Jessup of Jessup Preformance in North Vernon IN. Jim used to work as a designer for cummins and can do some very good tunes. Im sorry I dont have his number right off hand. Living close to him I have seen alot of trucks he has worked on and would very reccomend. Ive seen everything from mild to wild. He uses a laptop to reprogram the trucks computer not a chip. | |
