Well, I ran it...and ran it...and ran it. I threw it into 5th gear at about 7000 rpms (130 +/- mph) and this sob pulled HARD all the way to 160 mph and I let off the pedal and slightly braked back down to about 75 and the whole thing seemed like it only took about 10 seconds.
How are you getting to 130mph in 4th gear? Your sig says you have the track pack...did you swap the 3.73 gears for 3.31's? Even with your rear tires and a 7k shift, you're looking at 115 or 116 mph.
