does a g-tech pro really work?
 

I am thinking about getting a g-tech pro. Does it really work. How accurate is it? Thanks

some what...one of my friends had one the et's tended to be a couple tenths fast...like .3 or something. Not really sure about anything else, as far as pwr, or anything. I know it got really off and you could get some really good numbers if you didn't set it up when you were on level ground.

IMO not worth the money, it will just encourage speeding/racing and get tickets and/or jail time.

for me, the 1/4 mile et is generally within a couple tenths of my actual track times. however, the trap speed always reads high. personally, I'd save the money, unless you're very far from a track.

I have the new g-tech pro competition. It's really accurate where as the older model g-tech pro, you have to calibrate it just right. I tested g-tech pro competition on my friends car at the track and it was almost dead on with his e/t. The g-tech pro is usually off by a few tenths and the mph are always high.:)
