thank you for that informative answer JMR0360. this is just what thought about the tuners. i have always noticed the difference in gas tuners and diesel tuners and that there're are these incredible gains with the diesel in HP and TRQ but not the same with a gas engine, and as i have been told that if you cant get more air into the engine, like you can with a turbo, then you wont be able to improve the HP as much. as for the trans. shifting i would definatly get it if had something heavier than 3000lbs to two.
