    If not restricted and you are not making big HP, you will not see any benefit by removing it.

    You will, however, eliminate the possibility of the “killer bolt” issue by removing it.

    I live in Alaska, and if you get stationed here, you will want a functional grid heater.

    I hope this information helps with your decision.

    Re: Cummins - Grid Heater Delete Questions

    FWIW, I deleted my grid heater and added a Banks 3.5" intake at the same time.

    No code, no tuning change, though the truck was previously DRD tuned.

    First, mod/combo mod gave me a very noticeable increase in fuel efficiency. Rolling on 38's with stock gearing, i was averaging 19-22 on the freeway cruising at 60-65 (I have actually calculated, and my truck's computer is within .01 MPG accuracy), and about 16-17 mixed.

    After the mod, solid 23 on the freeway, 19.X mixed, and that were going over a pass that tank.

    The truck does chug for about 10 seconds on cold start now unless it is pretty warm out.

    I definitely will be using a block heater this winter.

    What mods did you do to get that increase?

    I currently have DRD tunes and an Air Dog installed.

    Just now looking into doing the grid heater delete.
