I hate to burst your buble, but I don't think there is a turbo that will clear smoke on 9x9. The problem is, you are most likey draining the rail, leaving a lot of fuel unburnt due to the low injection pressure and giving lots of smoke and high egts. Moderation is the key here. Try 5x5 and I bet its faster.
As for a good turbo, we need to know where you want the truck to be and what you are doing with it. towing with 500 hp requires a different set up than drag racing with 700hp.
BTW - Even with twins, with my 100hp injectors my TST with the twins program is set at 3x3. And I am somewhere over 600hp. And it flat hauls the mail! Some food for thought.
