I have a 2011 Ram and used the Diablo tuner on it and it has the option to turn the speed governor up to a higher speed. Been 2 yrs. since I did it so I don't know what the max was but I'm sure it was at least 145 as that's what I turned mine up to. I'm surprised you can only run 130 with that combo. I had my Ram up to 132 (gps verified) and it was still climbing at a good rate and I can't imagine my Ram is more aerodynamic than your car. Plus it weighs 4400 with me in it so it is close to 1000 lbs heavier than yours and it has 4.11 gears. Other than the tuner the only mods are a K&N drop in filter and cat back exhaust. In other words probably only a 10 hp gain over stock. Yours should do 145 stock
