I wonder how much of the hardware would be similar for the 3.0 and the M....
Tuning we can always go to ESS in Arizona. If I get the M kit I'd make the drive to ESS in Arizona to get the tune/install but, honestly with ESS's supercharger out there would have to be substantial power gains for less cost (since ESS already provides the tuning in their kit).
HPF makes some nice stuff thats for sure..
