ok using my imagination now................. so where you taking it to next time? gotta remember not many people know what theyre looking for, they just wanna see big power and it makes them happy, certain companies know this. i've seen rolling roads read rediculosly (i cant spell) over and some stupidly under too! only way you can really do it is get a few done at different places and get an average. just make sure you get the right graphs from them though. edit- here's an example. 2 rolling road graphs for my car. look at the difference both are WHP and torque - (hence y i say about 200@ wheels) http://i50.photobucket.com/albums/f332/hor...cars/gtpwr1.jpg http://i50.photobucket.com/albums/f332/hornet36/cars/rr1.jpg
