Re: how accurate are G- tech pro?
I have found the 1/4 mile times to be pretty accurate. The original G-Tech I have would sometimes lose its mind if I launched hard, the new one hardly ever has a problem. The RR version gives you a bunch of features to use if you ever decide to autocross your truck. The included software is fun to play around with but I'm not sure how accurate it is, a lot of variables are assumed to make the torque/HP numbers. I think it is generally repeatable, however. Neat toy for the price that does provide useful information.
