yea but doesnt gtech use the factory speed sensor, so any wheel spin off the line would be taken as actual progress down the track



i dont know thats just my outta the ass theory but it sounds like that may be the reason gtech thinks ur faster

i'm pretty sure the g-tech has it's own sensor setup. i can't remember the exact tech data, but it uses it's own sensor...there is a post on here somewhere that really explains it.

The gtech meters are stand alone units. The link to their site is in my post above. It will have accuracy data there.
