Air charge wot timing can you add more rows?

[AlleyCat]

I see some tunes that go to 1.90 on the air charge axis. Mine goes to about 1.6 or so. How do you add more rows on this axis? I did a third gear pull for my tuner and it got up to about 2.00.

If you change it your tuner will have to set timing in that way. I’d have him do it

He told me no need to do as any cylinder fill above 1.5 which is in my tune will use those figures in the 1.5 cell.
