slug below 2000 rpm

First I will start out with my truck. 03 so cummins 373 automatic. Since I installed my smarty jr my truck is flat below 2000 rpm. Above 2000 it runs great. I have tried all the settings and still flat below 2000 rpm. My fuel pressure is 18 psi. Just checking to see if any one else has this problem.

is it just rpm sensitive or boost pressure sensitive?
My Banks(which I know is totally a different critter), don't kick in until about 12-15 psi, no matter the rpm.
maybe your's is too.

I stacked my edge ez on the 40hp and it made a difference. It made it not so flat, and it was more responsive.
