73'Mach 1, Tnfastbk and c9zx offer sound advise, I would only add that Holley states that one should start their tune with the spark advance feature turned off and work off of your existing distributor advance curves.also get your IAC really dialed in , If you don't have air conditioning shut the ac kick feature OFF. it will help you dial in the IAC easier.-when you have your air/fuel FULLY dialed in and your learn tables are are almost ZERO then would be the time to let the sniper handle your ignition advance.I have installed a few of these systems on friends cars and found that there are 3 different levels of tuning, if you allow the system to only self learn, you will probably be disappointed.Don't tune by numbers, tune by what YOUR engine likes and what it does NOT like.Boilermaster
