does this thing really work like the commercials / website say it does?

if so that's pretty damn cool. but for something like this, that price seems really low.

 

Yeah.

 

yeah...it is...how does it work?

 

from what i have heard these things really work. But as far as how accurate they are and all that i dont personally know. If you get one keep us updated

 

This is just from what I've heard

They work pretty damn well, and are pretty damn accuarte. If you don't have the money to go to the dyno every once in awhile i'd say it's worth it

 

i was reading forums and it seems pretty accurate. i think it NEEDS to be on your windshield (?). i think it feels momentum from your driving, and "listens" to your car (dunno if it's audible or from the electricity in the cigarette lighter).

looks like it maps out your driving too. i think it's sweet, maybe i'd wait a while until it gets better and better.


i didn't see any posts there that compared it to actual tests. i know if i got one, i'd go get a dyno right away to find out, and probably get some times at the track.

still, that's sweet.
