Predator for Silverado classic 5.3

Adjust spark from 2-4K 4-7k on 93 performance what would be a appropriate adjustment

the WOT timing is already jacked up higher than stock in the diablo tune.. I wouldn't add any more..

in fact, I usually have to LOWER it in custom tunes for people due to knock retard they have from the timing being too high in the preset tune already.. so yeah, I would not add any more to it..

but it's up to you man..

Ok what about injector slope? Feel like I can get more out performance wise than what I'm getting

[06MonteSS]

don't adjust anything until you've done some data logging to see if it even needs any adjustment at all.. and which way you'd need to adjust it.. you don't want to just change things willy-nilly without knowing what it's doing..

Numbers in the LIFT add up anywhere from +1 +2 is why I was asking
