What you change depends on where you're starting from
and where you want to go.

A stock(ish) vehicle may not need airflow (MAF, VE) to be
touched at all. I would look at some of the timing and fuel
behaviors that dog the trucks, like over-enthusiastic burst
knock retard and delayed power enrichment. Copy what you
see on cars of similar compression ratio, as a first stab.

The best thing you can do if you want to be a good tuner,
is learning to log the right things and understand what that
is telling you. Otherwise you're a blind man with a shotgun
and that always ends well.

Thanks Jimmy blue! I do know how efi engines work quite well (4th generation autotech) but I still have tons to learn as far as tuning
