Interested to hear your comparisons. I went from a 2011 to a 2014 and was amazed. Even with a tune and pulley on my '11, the '14 feels like it's still 125+ horsepower ahead of the '11. The 2014 has a stiffer ride than the 2011 which I take to be a "200 mph" suspension versus a "155 mph suspension" (LOL). Third gear in the 2014 feels like second gear did in the 2011. Being able to take 2nd gear to 90+ and 3rd gear to 130+ mph is an adventure also. I slammed it into 4th gear the other day north of 130 mph and it broke the rear-end loose. No chirping the tires but actually broke loose and required a little "corrective" action on a three-lane interstate. A little (okay a lot) unnerving but fun as Hell. Most amazing is the improvement in my gas mileage. Yeah, pretty crazy but I've always tracked it pretty closely in my cars as they are daily drivers but if driven sensibly, they return surprisingly decent fuel economy (for a supercharged V-8). Enjoy your new ride, I am. :rolling:
