I have a 2014 ford f150 with exhaust and a k&n intake. I'd like to get some more power out of it. I tow a lot and would like to see something to help with the lack of power. It's a 4x4 and it has 33'' tires. Probably need to put some 4;10 gears to really make a difference. does a tuner really help that much? I've heard of people doing the boss intake mod but that's like 1500$ is it worth it or is the something else i need to do Thanks.
