Can anyone tell me how to fix my speedometer issue? i finally got it working again today, and figured it might as well be accurate as well

Same here. About 50% slow. :roll: Wrong ratio box most likely. I'll probably get one of these, since I'll be putting bigger tires on later- http://www.dakotadigital.com/index.cfm/ ... prd126.htm

Since yours is a 90, is it mechanical? Mine's electric.

The NV5600 affects nothing.
The ratio box, as you well know, is attached to the t-case.
Just suck it up and buy the ratio box at the 2nd link above. :lol:
There's very few places that offer this stuff and their quality is as good as anyone else's.
