Helix Power Tower, Is it worth it? Any "seat feel-able" gains? A buddy of mine bought one for his taco, (lifted 2wd) and swears it has made a difference, but i can't tell at all... His has the 3.4 too. What do ya'll think?
3.4s are direct port injection (meaning air and fuel don't meet til they are in the combustion chamber) rendering those things useless;swirling air doesn't create horsepower or MPGs.
