First off, I’m sorry if this is in the wrong forum, I was confused between this one and Electronics.

I am looking for a hypertech like device that can hook up to my Gs’s computer and display my average miles per gallon, average speed per trip, 0-60 time, ¼ mile time, and maybe even tweak with my horsepower and torque numbers. Does anything like this exist for our cars?

Any help is greatly appreciated.
Thanks
