im sure i dont just NEED a msd ignition with my mods but i already have one that i havent used and was wondering about putting it on. someone told me that it will throw the computer off or something like that is that true? and will i benefit from putting it on as far as a cleaner burn or help on fuel mileage. also what gap should i run with tr6 plugs? the box is a digital 6(the older one with the dials on it)

There is no harm in using it. I run my 6A with the stock plug gap.
