What are you racing at Avalon? Take it your out at the dirt track.
I did also find this:

I haven't had a chance to play with an ls1, let alone mafless so just lots of reading at the moment.
Looks like even when running with MAF need to get VE tables sorted down low.

Looks like case closed, ten dyno pulls and no safety mode with 30% added to the "predicted airflow vs rpm vs tps" table

Thanks everyone for their help.

Like i said before, this is a trap for people tuning modded, mafless, ls1's.... Oh well, at least I learnt something

It was a big thing back in the day when people first started tuning the VZ's. For the more wild combos, you can max out the tables on the dyno then create a histogram to populate the tables, then add a margin say 10% and that's your safety. Its part of the ETC safety mechanism.
