Gear ratio snafu

[Gustav]

So, the rocket scientist that installed my supercharger put in a 3.72 gear ratio thus overriding the 4.1 that was already in the predator tune. The correct one is 4.10 BTW - I checked.

I drove about 375 miles before I checked and entered the 4.1. What happens with a wrong gear ratio if left alone long enough?

Not sure I am following this, but it sounds like you tuned the truck for a 4.10 gear, but you actually have a 3.73?
Just reenter the 3.73 gear ratio in the tune, and all will be fixed.

Thanks

The supercharger installer put in 3.73 and it should have been 4.1 (which it originally was in the accompanying predator) i.e. he changed it from 4.1 to 3.73.

I have since corrected it to 4.1. My question is: what kind of damage, if any, would occur if the incorrect gear ratio was left in?

Nothing substantial. 3.73 to 4.10 is not that big of a jump, if you went from 2.73 to 4.10 then you might have issues during shifting but no real damage would occur.
