i had intentions on getting a regular ts 6 position "no custom tunes" but i found locally a used BULLY DOG 40420 TRIPLE DOG GT PLATINUM DIESEL DOWNLOADER for less then 1/2 the price of a new TS 6 Position Chip my question is are they any good my truck is a bone stock 2000 7.3L 6 speed 4x4 looking for mostly gas mileage gains its not a drag truck or a sled puller

 

100% junk on a 7.3 IMO, i will never run anything but custom tunes again. the TS6 is good but the hydra is better
