*UPDATE* Hey guys. i was on the freeway and i was doing 90-110 and for some odd reason i could helaa hear a grindin noise. i have no idea what the heck it was. i havent programmed the computer for the gears but it made the car slightly shudder barely noticable... how can i explain. Remember your tonka trunks? when u put your weight on it you would hear the tires make a somehwat grinding noise because it was scrapin the bottom part of the tonka trunk against the ridges of the tires?. that lil noise?? yeah heard it on my camaro at those speeds. what the hell??? it didnt make that noise with my original gears
