96plymouthturbo,
Backfiring under load (especially into the intake, though it might be hard to tell) is a classic symptom that you are too lean. You need to increase the VE table entries in the higher kPa parts of your VE table.
BTW, it is much better to post an actual datalog than a screen shot.
Lance.

could it maybe be the fact that i am running to "hot" of spark plugs for my application?? i am running a 1996 dodge neon with a custom turbo setup with the stock heat range spark plugs...i am going to try to ranges colder tommorow to see if that helps because i am running at a a/f ratio that is suggested for my setup.

with hot plugs and turbo its more like detonation
