I am selling a G-Tech II SS. Its one of those things that tells you 1/4 mile time hp, tq, 0-60 times. It really does work belive it or not ,but I am kinda in a pinch for money so even though I just got it not that long ago I have to let it go. I am looking to get 170.00 for it. If interested e-mail me at vdubbri@yahoo.com. thanks Here is a link to their sitehttp://www.gtechpro.com/
