I have a msd digital window switch with my nitrous kit. im about to spray 200 shot i dont want the rear end to go out.

Now im about to buy thi sproduct here http://www.harrisspeedworks.com/shop...3&cat=0&page=1 and i also wanted to know if i should get a MSD ignition 6AL and a blaster coil. Or do i even need the coil?

Reason im getting the controller is so that i can spray 100 shot off the line then the full 200 after 4.2k rpms all the way to 5800 rpms (where my end rpm is)

Also i do want to retard timing for n/a runs and nitrous runs. Because when i race and want to turn the pregressive controller down alot of percentage % (25% start and 50% end which would be 50 shot starting and 100 shot ending) I would also have to add some more timing hence the timing would be pulled for a 200 shot.

Or would i even need to have a tune to pull timing if im get the MSD 6AL and a Timing retard box? SInce the timing retard box has an adjustable ****.

Please let me know if this makes any since to you.
