I think mine will b in the 12's. My last one was. Sct is the best IMO for goin fast. I have a setup on my gt500 from them. But the tune on my truck was done by my good friend from svt. Great pull and solid shifts. I'm sitting at 460 hp right now with just a tune. I just got it the week before Xmas. I also have a track 2 miles away. I can't wait to get some times. 13's with a big dog huh? Love it.
