I just got It, and its pretty dam cool. It does a lot from measuring RPM to HP.
It has a shift light on it which works very well (it has four lights one comes on 500 RPMs before redline, two come on 250 RPMs and all four flash at redline) I have not had a good run to measure HP / TQ. It also measures G's of course and has cornering lights, which come on when your car reaches is G max. And also the basic 0 - 60 1/8 mile 1/4 mile. It probaly does more but haven't had had a lot of time to play with it yet. also you don't have to perfectly level it like the older g-tech which is good.
