Bingo. Its the module they THINK could use improvement! I have done the HEI and Mopar EI swap and noticed no diff other than not having to use a ballast. It was done on the same car,one after the other. No diff in start up,idle quality,or seat of the pants feeling.
You think mopars are boring because you see 100 of the same? How about a chevy and seeing 10,000 of the same thing,try that for boring.
