Try running about 18-20 psi in the rear tires and 32-35 in the front at the track and make sure you drive around the water box. With street tires the water gets sucked up into the siptes and then runs out at the starting line... just do 1 good dry hop to clean any crud off the tires and then stage. Not sure if your holley box has an external input to retard the timing - its another way to build boost on the line, it puts heat into the exhaust manifold.
