If you're gonna BOMB your truck, a fuel pressure gauge is about as important as the Boost & EGT gauges.HemiMagnum said:Fuel pressure: not many people have this, but will help tune your lift pump and let you see if you are running out of fuel. Nice to have to see if your lift pump is worn out.
I love watching mineHemiMagnum said:BOOST: Tells you if you have an exhaust leak, and can also be used to tune your truck. More boost=more power. It will show you what your mods do for boost. It also helps with mileage if you drive by the boost gauge. Less boost=more mileage. Also a fun gauge to watch
