just wondering if anyone out there has a g-tech and has taken measurements before and after mods. i know that the g-tech isn't extremely accurate or anything, but at least that would give us a general idea. much better than this butt-dyno crap i keep reading.

 

ah yess, lets take a look here... Stock xBs seem to run 0-60 in 10 or sec. H/E/I would pit you around probably a 9.5 if your good. So its better to go with the but dyno, then the cold hard facts. If you look at the cold hard facts a 141whp xB still runs the 1/8 mile track in something like 10.7 I had gotten my Focus ST to run times like that & I suck at draging..

 

those g-techs dont work for sh*t...ive used one and ran at the strip and they are very inaccurate

 

ok first off, i really dont care about drag racing. second, i'm not looking for real accurate results, just consistent results that you can compare to eachother rather than "it feels faster." thats what we call the placebo effect; when you install a new part, you subconsciously want it to be faster so its always going to feel faster.
