    I have a couple of friends that have them in their 1/2 ton pickups and really like them said it made a very noticeable difference and their gas mileage went up about 2 mpg.
    Just wondering if it makes that much difference in our 5.3 they dont seem to have as much torque management as the trucks.

    Sorry to drag an older thread up but I would assume with our itty-bitty transmissions, we would be the ones with a lot of tq management. I personally am having a custom tune done next week. Bought a second ECM so I can just swap back and forth for warranty work.
