    Welcome to the site! It is a little expensive, but have you looked at the Banks system? For the big block and towing Banks makes some really effective products. There are some "tuners" on this site who can possibly do your computer, also. Good luck!

    ECM programming

    The timing is controlled by the ECM. Normally you do not have control over this setting.

    A couple of things you should check out.


    Adding a tow/haul switch to your truck. See the info here:
