G-Tech Pro
 

Has anyone used a G-Tech Pro and is it fairly accurate? Either the old G-Tech Pro or new $250 G-Tech Pro Competition.......

I am happy with the regular G-Tech.
It was with in .2 tenthes when a friend ran his car at the track.

Is this hard to calibrate. I heard you have to know the weight of your car to get accurate reading.
As 0-60MPH and 1/4 mile right?

No, you only need the weight to calculate your horsepower. Makes no difference in acceleration numbers. My experiance with it was pretty good, within 1 to 2 tenths off. And that was the old Gtech Pro. Plus I love hooking it up to everybody's slow car to see what it runs, it's pretty fun.
