Thanks for the input on propane guys. Ok I've got a 2003 HO 6sp 4wd dually quad w/3:73 slt. I do some hauling 20ft cattle trailer but mostly just commute 120 miles a day on the hwy. Its a virgin copletely stock. I want to build her up but not sure where to start. Looking for input on comps, intake and exhaust. Improving my fuel milage wouldn't hurt either currently getting around 16 usually driving around 70.

 

gauges first then go from there....

 

Agreed, guages first.

 

After your gauges are installed, you will see there are some options on the market for raising the fuel pressure on the common rail system. It would be a safe upgrade to put a mild set of injectors in rather than raising fuel pressure. By raising fuel pressure it can be a risk due to the injectors can leak. It can cause engine damage and it's not the best way to get the raise in power. You can raise the HP up from 40hp and up by installing larger injector nozzles. <br><br>The DTR will have the EDM injectors soon on our store. So if you would like some info just send me a PM.<br><br>Hope this helps.<br><br>Don Ramer
