I've been useing the Mopar Blue constsnt out put regulator with chrome box for years. Never skipped a beat. Been on this car 3 years and my last 440 six barrel car for 5 years. I allways make sure i have good grounds. Never had any problems. Local speed shop here is mostly mopar guys and they install them with every mopar ECU. I've only used the mopar part never used the summit or other aftermarket brands.
