| Fuel and timing, Timing is the HUGH problem. If one programmer adds 1/2 a degree and the other adds a full degree you have to add them together. This COULD cause engine damage. Duramaxs arnt like the f350's a extra defree of initial timing on a duramax is like 8 degrees in the f350. I still would not do it. Just my opinion.
