depending on how many lbs of boost you plan on running you'll prob pull out 4 degrees on the top

I will be making my timing map so pulling 4 degree gives me no clue on max timing advance.
i'm looking to find numbers like 34 degree's or 36 and looking at hi rev figures because from the oem timing map there's more advance somewhere between 4 and 5 000 rpm than past 7000

Not sure if it's any help, but we run our NOS Top Gas bike at 41 degrees, and ramp 4 degrees retard out as the NOS is being applied. We run a Schnitz Pro Series II ignition. We received a reply to some questions from Ryan Schnitz, and he basically had the same numbers we are running. Sorry if it doesn't help you on a turbo application, but thought I'd try to help out if I could.
