i went to the track on sat. for the first time with my truck. my truck is mostly stock except for a muffler and cat delete and my edge mileage max (25hp). i have 305 good year mtrs, not the best choice for the track, i launched at about 1800 rpms, ran it several times for a best time of 15.9 at 86 miles an hour not bad but i still lost to my buddy 7.3l with an edge 100hp tune, can't wait for my sct. all the other times i was haveing traction issues due to the limited slip not holding (detroit locker future mod). i didn't launch in 4x4 for fear of breaking something and i figured i would loss the time up top would it have been worth the 4x4 launch?
