Here's another idea, and actually a couple issues that I faced too. First, is your bov/dv venting to atmosphere or recirculated? These maf based cars like to be recirculated back in the intake after the Max, but before the Turbo. Also, what size maf housing do you have? I'm not sure about the 30# software that you have, but I know that a lot of the c2 software calls for a 4" housing. Just some food for thought.
