Cummins dual cp3

companies make a controller for a reason…do some searching, usually fish is the go to.
 
I believe H&S uses a fish tuning controller however the OP is asking about fleeces kit that doesn't use a controller.



You would need hp tuners or efi live to run it.



You can buy H&S either way. I prefer running without a controller. IF your tuner will support it.
