MRL Mild 440

The MSD 6's are known to retard timing at RPM and are also prone to some other weird maladies.

RAMM - Never heard that before, nor had any weirdness. Was this personal experience?



Mike - What is this new box like? A factory style ECU box or what? I've removed FBO product before. It was overpriced, not working as advertised, and after some snooping nothing remarkable. But that was the ECUs and recurved distributors. After my experiences with them Joe's comment wouldn't surprise me in the least.
