Cummins ecm question

Cummins diesnt require any calibrations as far as engine to ecm like detroit or volvo do so really it is plug and play u can turn up the horsepower if u want but as far as evrything else goes its all the same the only thing that changes the horsepower are different rations for fuel and boost and ect. Youre mechanic was right if u take ecm from orher vehicle u have to calibrate it to the truck but u can swap engines all u want as long as its not a serious horse power difference between old and new its no prob at all

 

I sugest no big CPL difference so I'd use it w/o recalibration

 

if you want cummins will do a uprate tune for 350 dollars took mine to 550 hp and they advance timing a little and it will bring your engine to life also I got 7.1 on a 2006 isx volvo 670 13 speed running 65 to 68 all the time. If this was a company truck they really choke these engine back. Plus there is nothing they will do to harm your engine. The price might be wrong had mine done three years ago.
