And if you want a custom tune...I'd find a local GP forum...and see if anyone tunes there. For the GenV you need to compinsate for the more efficient supercharger. Like they said...a 3.4" on a GenIII is more like a 3.6" is GenV...you'll make as much power if not more, with less boost, less heat...and less parasitic loss.
so dont put the 3.4 on ?
