I have been looking at stage 3 motorsports phase 4 performance kit...which includes S&B CAI, 80mm throttle body, kooks headers and Xpipe dual exhaust, and choice between 2 diff tuners. Now, this will run me about 5k...am I better off just saving an extra couple thousand and buying a whipple or rousch stage 2 supercharger? I have a 2011 with 63k miles on it. Pretty much all stock. Bought from local ford dealer last December and have put 3k mi on it so far. Any help is appreciated and thank you.
