I can't figure out which would be better for turbo & nitrous so I wanted to get
some Ideas on why u would chose one over the other or could I do both cause I
like the idea of havin emanage cause I can control fuel but can't amp up the ignition
like the msd but I could go safc with msd ..... what to do

Yeah you can do both. I did and I really noticed some improvment. I used to have a missfire problem when the boost really started to come in. At this time I only had the e-manage. I then put the MSD-DIS II on and no more missfire. By adding the MSD you can use one of the rev limiters for befor you launch at the track. You also get multiple spark discharge which can improve fuel economy and horse power. Also you get more energy into the coils which improve spark energy. Then with the emanage you have the ability to control timming over a larger range by using the 16X16 map for ignition timing.

Just my 2 cents
good luck

Thanks for your two cents just what I wanted to hear
