Everything is pretty damn on par. I mean the obd2 is giving your device live info. It might be a millisecond off sometimes but if u look at your rpm gauge and the one on your device/tablet they are on par same thing for speed and everything else. There are so many options from every little detail like combined average mpg consumption to intake vacuum pull and engine load/stress percentage when you excelerate. Every temp that your ecu records but doesn't show on your standard car gauges it shows. It's very accurate. It's the most fun thing I have added to my car besides intake and exhaust. And it will show those temps to and fuel pressure. Seriously you can spend hours learning all it offers and custom screen layouts with what you want it to show. The app also looks badass on the dash with the tablet showing all the gauges/read outs.
