IMO it depends on your goals and what you are trying to accomplish. For the bracket guy Oil press, fuel press, trans temp, water temp and vacuum would be all I would be concerned with. It comes with the G meters and voltage and driveshaft RPM. IMO driveshaft ROM and G meter will tell you a TON about how the car is working. Many people overlook the G meter and wheelspeed early in the run, it is the difference between and great running car and an average running one. As for engine vitals, engine vacuum will be your best friend here as far as ring seal and overall engine health. Oil pressure is nice the rest just seem to be stuff people want to see.

As for me I have a ton, never a thing as to much info...
