does it raise fuel rail pressure or just manipulate map sensor readings on the cummins?

Still wondering if the shim kit comes with the power puck and if it will work with the edge juice with attitude, have been told by a couple people it will not work?

is this included with the power puck?

I am interested in some info on the power puck for the 08 6.7l cummins, i am wondering if you have to shim the fuel relief valve like with other units( IE ts mp-8) I also use a edge juice with attitude and wonder how this stack combo would work out, any input would be appreciated, Thanks Sean
