Hi JR, How are you doing? When I got the car I didn't get the cam card but the guy told me it was quite a radical street cam from Comp. This thing shakes and rocks at idle alot, in fact the antenna shakes about 3/4 inch at the stoplight in drive. Sorry I could not be more help. Line-lock, yes. It's the only way to do a burnout without killing the rear brakes. Racing is fun.jr said:What kinda cam are you running and are you using a line lock?
