DarkHorse16They would be putting it on a dyno to show the proof. even if its 405 I'd be happy. and thanks. I'd love to do long tube and midpipe but I don't have 2500 to dish out on headers and midpipe plus install. 800 on intake and tune is much more affordable.
DarkHorse16The gears are beastly. first and second gear are so mean
KHvistagtWhat supercharger did you go with? What did it cost? I have a 2008 and am not sure if I want to supercharge, turbo or just upgrade to a 2013 or newer.
