msd install...retune???
 

im about to put a msd ignition system in my 463whp turbo civic. digital 7 plus, msd dizzy, coil, ect ect... would it be smart to get a retune??? im really just curious to see if i pick up any power over the stock ignition. im doing it because it will give me more potential, not to pick up power now. just curious though. lol

In theory the hotter spark will lean out the mixture just a little. I'm not sure what the multi-spark will do to your a/f and ignition timing down low either. If you have a graph of before, it'd be good if you could jump on a dyno and make a couple pulls to see where it's at. Admittedly I'm curious about this myself as I have a digital 6+ waiting to be fixed and installed and want to know what it will do.
