Your truck monitors a lot of random stuff but it doesn't display it. the Ultragauge just provide a read out of what the truck already monitors. I bought mine mainly for fuel economy so I could change my driving habits but it monitors other stuff like intake temp, engine temp (haven't used it for much else). You can also set alarms on it so it'll start beeping when you hit one of the set points like mileage for an oil change, engine temp too high, remaining fuel too low, etc. It does not alter or have the ability to alter anything within your truck's CPU to enhance performance.
