Would you mind sharing your table?

My truck has a LBZ CP3 now, but it's a 12mm stroker, so I just made that table up from scratch, for fairly obvious reasons.
I'm on my phone, but I found where I posted it elsewhere. It doesn't vary much, but I know I had to tweak it a little in a few spots.

Crank it up diesel currently tunes it but i will be getting tunes from mark here shortly. Waiting for my hoses and regulator to get here and need to rebuild the filter head. Then i will go from there. If its a weak pump will the lift pump help it keep up with rail until i get a new cp3 or will it not change?
