Okay, the 13.49 was achieved with the nitrous last season with an F303 cam and 4.10s(I agree was over cammed). Since then I added all the mods on my sig. I am not running the nitrous when I say that I can't run with the Z28. You are right, with the nitrous I should be in the low 12s easy. For now I am just worried about it without the nitrous. The system is a wet kit. When I had my buddies 24#ers in it, when it was cold it would pop through the intake, as soon as you drove it a little it would straighten up. I don't think I can get the FMS MAF calibrated for 24#ers. Something is restricting the engine, honestly is the 30#ers way too big? When I bought the Holley Systemax kit, it recommends either 24s or 30s.
