burn time should not matter as far as a misfire is concerned. if the problem is only at initial accel and idle check for vacuum leaks. is you ignition timing set correctly? are you using ngk plugs? are the injectors leaking down?

msd 6al box (6al is the system designation) its the type of red box that msd gave you and depending on the system it gets a different label.
