    shoulf be about 6 6.5 stock ..your charger may be slippping a bit ..or you could have a small boost leak..or the guage may just be a little off ..its normal..especially for the lower end guages..

    the best bang for the buck is a used x charger and a set of 42# injectors...you wont believe the acceleration difference..
