Will I get trouble codes when I change the ratio of the differentials?
I have a set of 4.10 ratio differentials that I am going to install in place of the stock 3.90 stock ratio diffs.

Two questions:

Is there a way to correct the speedometer to show an accurate reading?

Will the change cause trouble codes that result in dash warning lights that I can't get rid of or cause a failsafe limp mode?
