So I've been wanting to do it for a while, and finally bought a bullet and ordered the kit and a new filter. Overall it took about 4 hours, but I was really taking my time and double checking everything. Took it out for a spin and it's crazy that my 6100lbs Pro4x can chirp when shifting into second gear. When driving normally you can sometimes tell its there, but it's very, very minor. When flooring it, you feel a huge difference.
