L-SS-1

i just put on a ls6 manifold and 28.8# injectors on my 2000 SS, and i checked the spark percent on the real time data, and it reads something like this...
at idle....about 28-30
normal driving 30-40
hard driving 35-40

so my question is what is a good percent to have and if this is way off, then what should i set the power enrichment level to as well as the W.O.T.?

P.S. some other mods include long-tubes, ORY pipe, and all other basic bolt-ons

I think you're going to want more tuning than the Predator
can do. You just upped fuel shot by about 9%. Your spark
seems normal to high. "Hard driving" may not be WOT. I
expect you will top out at about 30 degrees. You may want
to pull out PE (-%) because the fuel shot is increased by the
injectors. Hard to judge mixture by the in-car O2s; with
headers, more so.

I expect you might also run into some part throttle ping with
having killed the EGR. Maybe the injectors will cover that.
But really you'd rather have the spark adder table put flat.
