I think its the maf readings, will try to do a maf map, but I only have "stock engine" live data from techstream and it doesn't show voltage of the maf, only gm/sec.

You should be able to see MAF in and out voltages in the FIC software. Did you clamp your MAF at 5V? I really think there are much better alternatives to the F/IC. I'm still considering an ECUMaster ECU. Have to do more research first though.
