Allen spent about 4 hours with me yesterday (and it was f'n hot outside). He tuned until he gave up. Apparently, my MAF set-up just can't handle big boost set-ups. We're gonna convert it to a speed density tune. I left it there. Hopefully it will be done before this weekend!!
Will post up results asap.

Good luck man, I am probably following in your footsteps before too long.
I want to come up for a ride in that beast!!
Gone, but not forgotten!
It will be worth it when Allen gets that tune right. I think I'll be getting a SD tune myself soon. Also I'm sure I'll need 60LB injectors. I ordered a boost controler and am installing a water to air intercooler. You going to the Temple GTG on the 19th?

The nice thing about SD tuning, I'll be tuning for boost instead of RPM.
It's hard to find a middle ground when 1st gear will make 10psi at 5Krpms, and so will 4th gear, but at 2500rpms.
Plus, the maf is so far behind with this truck, there's just not enough tuning there.
I'll try to get it done this week, but more than likely early next week, I have these three truck in front of you.
But, it will be worth it!!!
see ya soon,
allen
