cant smoke the skins...problem??

The only difference between the stock, orange, chrome and gold boxes is the max rpm they will support. They will not have any impact on the low end loss you are experiencing. An MSD type ignition that makes multiple sparks up to 3500 rpm or so will help the bottom end.

A conventional points or electronic ignition (not CD like and MSD) requires current flow through the coil to create a magnetic field. This magnetic field takes time (refered to as dwell in auto speak) to saturate the secondary windings and allow the coil to generate a voltage potential and spark. As rpm increase the time available to create the magnetic field decreases. So, just when you need more output out of your coil at high rpms the coil is producing less. The various performance ecu's from mopar use better faster acting components that minimizes the drop off so the igntion can support higher rpm.
