Doing some Dyno pulls, a question?

[BrutalMetal]

what spark advance through the powerband at WOT should I be looking for? I'm currently at about 20 when I datalog but I've heard guys go as high as 26 is that correct? I presently have Zero pinging and would love to bump it up more if safe, Thanks!

You should be able to get a few more degrees in there, but every combo is different, so there is no magic number.

Thanks Mikel I currently have the 93 Octane performance Tune loaded with 2% spark advance added to both rpm levels, how much more should I dial in? Like I said I'm at 20 degrees now, could I go 4% or would that be too much?

There is no magic answer....have to test.
