I recently bought one of these and havent used it yet due to the weather and was wondering if anyone else has?I kicked the idea around for a while before buying it but i've seen some good feed back on them.Anyone actually using one that can give me some feed back on their performance based on actual experiences?</P>


If not ill have to wait until spring to know if they work and how well.</P>


Its the $250 one not the little led readout.</P>

 

Well I have the Gtech Pro and it works great. I took it to the track a couple times with my friends cars and the numbers were exactly correct. The only thing that was off was the mph. It was off by about 2, but the ET numbers were exact. It is also suppose to be accurate within a few horsepower also.

 

i have heard storys of them reading as much off as 6ths.
