looks like you need more fuel. The maf can't be maxed there are people on here with 15+ psi with the stock maf. Plus at wide open the maf isn't used PE is. Looks as if you need a better fuel system.

umm could be maybe the injector were maxxed cause we watched fuel pressure and it only dropped maybe 2psi not to much
not that it matters now since i took it off and but the bottle on her.

Could be maf max, or fuel pump or injector max. It also looks like there may be a valvespring issue. Disregard what the guy said two posts up, the maf IS used at wot. The map isn't even used over 4krpm. Also, there is noone with an ls1 running 15psi on a stock maf without involving one or more of a variety of tuning tricks to work around the limits.
