There is no way it will go better than mid 12's unless you have some slicks and suspension mods. To run real good times you have to launch with it and all that extra torque will make traction difficult. With slicks, suspension, and a kick ass driver...never know. A typcial stock GT is a 13.7-14.2 dead stock...and not many people get in the 13's stock..VERY few. Most are 14.1's. So you could drop 1.5 seconds or better off with that much nitrous but you need traction.
