If it has a knob, it may be timing controler. http://www.supercharger.com/Shop/ViewProducts.aspx?PlateIndexID=33959. I don't think the sandard JR powercard has a knob.
I know that Rose does not want to spend much money, but a PC Pro card from FFS can fix the drivabilty issues. Ask Tom Arnold. His JR SC was nearly undrivable. Low power, hesitation, etc. I stripped off the Apexi SafcII controller and plugged a PC Pro and it was like a new car.
