You should be able to dip into the 12.9's on motor. How is the tune of your car, meaning, how is your fp and timing set?? Do u have a bigger fuel pump? You should try 16* timing. I'd get a set of dr's and play with the tune of the car before resorting to nitrous to hit 12's. Is your tune up fresh also? Answer my ?'s and i'll try and help when I see your answers. Fwiw, your mph seems low for your combo, but spinning on a street tires sin't gonna help it.
