I run a Hondata as well.
You can see my #s in my sig. Was your 12.4 on street tires?
I'm currently running 2" piping on my T3/T04E and I don't think I push enough CFM through them.
It bothers me that you make that much power on a stock block when I don't on a built one (except for sleeves). I am running 9.5:1 cr, but I ran 12.9 psi on my last dyno...
arg!!!
Nice setup man!
