H2BRUTE is off the scale
Default ENGINE BREAKING UP AND MISSING BETWEEN 5000-6000 RPM

Recently, when I happen to rev the engine between 5000-6000 rpm's (only to hear the exhaust with the QTP exhaust cutouts open) it starts to miss and break up. This never happened before. I have a magna charger supercharger installed with MSD wires, new plugs, 178 degree thermostat, dynatech long tube headers with flow through cats and a bassani dual exhaust system and a Volant cold air intake. For the first few months after installing the supercharger, this never happened. It Always ran smooth. Any ideas on what might be causing the problem?? As always, your help is greatly valued..BRUTE
