Default Tuning a larger TB

I just installed a FAST 92 and LS2 TB on my wifes99 C5 H/C car. Haven't done ANY tuning to it yet, but as I was afraid, it is a DOG at low, off idle rpm.
When I installed a FAST 90/90 on my car, it acted the same way, but I sent the TB to Tony Mamo for porting and it was as crisp as my Z06 intake and stock ported TB.
Question: Should I send this one off (it was supposed to have been professionally ported) or can I just tune it out?
(The question is a little retorical, since I feel it can be, I've just never had to before)
Thanks
