I hope somebody can help me! I'm having an issue with my gauges going out at high rpm. I don't know what the issue is and nobody seems to be having this issue either. Any help would be great! Like I said it only does this when i get up near red line, not even to it. Don't know if any of my mods have anything to do with it. It has an Alta CAI, MSD ignition, Alta 15% supercharger pulley, ATI 2% overdrive pulley, M2 racing header, and Invidia cat back exhaust. I have a video here of it doing it. Its in the first 15 seconds. Thanks!

 

It's possible that the combination of your overdrive pulley and the high RPMs are causing the alternator voltage to climb high enough to cause an electronic malfunction. This shouldn't happen under normal circumstances so it might indicate that the voltage regulator inside the alternator is on its way out.
