G-Tech ...Pros and Cons

I use a gtech an old Pro model is it great No would I consider the #'s from it true No. Is it a great tuning device Yes. Numbers so so accurate. I don't have a close 1/4 track to test it on but if I go to one I will compare it. By using a 1/4 mile to 1/8 conversion chart it was fairly close to what I ran in the 1/8. Also it is good for back to back comparo's, which you may not be able to do at a track.

its an accurate tach.

I've heard that the track times 1/4 mile wise are usually within .2 of actual times. The hp/tq thing is useless though, and it measures trap speeds differently than the track does.

The new G-tech's are rather impressive. I take mine to the track all the time, very very close to actual track times. The hp/tq figures are not the same as using a dyno though, b/c it can't acount for wind drag, if used just for tuning, it's great.
My old G-tech pro was a little optimistic though

How does it compare to actual track times?
How accurate is the HP and TQ compared to "real" Dyno #'s?

I tried my friends newer one and it said I ran a 13.5, 13.6 and 13.4, all at 103 in the 1/4. Id say its okay for street use, but if u really wanna know, u know where to go.
