basicly you just need a bottle, rugulator, shut of solinoid, switch, and some hose and fitings. its real easy and pretyy cheap it took me about 2 hours to build the system from scratch, but you have to be careful because if you add too mutch your engine will blow up. Im not using it as a power adder Im just trying to increase my mpg so I dont use verry much only about 2psi. Just keep in mind Ive only had the system for about 2 days so Im no expert on propane injection. So do your own research. Any time you start moding a diesel the first thing you need is EGT, boost, and in your case a trans temp guage after that mod away

 

The 3200 spring gives you a wider power band, makes truck more responsive. As far as tuning your pump goes, you just have to play with all the adjustments to get what you want ie good power,minimun smoke and your egt under control.
