Yeah, it need to be tune bad for your mods. Two of the members here just ran 12.8's with setups similar to yours. Good run though. Last year I ran a 13.4 @104.2 with the mods in my sig, so I would say high 12's should be attainable for you.
12's are hard to get down here, because of the high humidity and 100* year round weather.
But i will sure try.
Waiting on cooler weather to bump timing.
I'm running on 3.2" and 17* right know.
Can you say 20*?
