Okay so today I saw a msd piggy back ignition module. I was wondering if any 3.8 owners have used one to raise their Rev limiter and increase the amamount of fuel being burnt. I need to upgrade my ignition system soon and am bouncing the idea of using this to help do it. American muscle says it will work, but I've only seen one used on an old carbed 350 so I'm not sure how it would work with a computer controlled engine. Any thoughts? I need to do a upgrade soon because I can smell the raw fuel coming out the tail pipe even after the cats are hot and working. Is it worth the $250 or should I just do a msd coil and wired with better plugs?
