Hey guys! i have an 2007 crewmax with 5.7l, and i went to the track and ran an 14.6 all stock. Im wondering what parts to buy to get the most horsepower. Im thinking about the volant cai, and was wanting to hear about what other aftermarket parts yall had that made the most improvement at the 1/4 mile besides the supercharger... I just cant come to terms with dropping $7000 on a supercharger right now. Thanks for all input and info.
