Yes speedo/PCM will need recal with any ratio change. 5min job.
my diff had to be rebuilt , so at the time i changed ratio to 4.11 ( hardy ever any freeway running).
Does this affect the speedo at all, as in does something need changing.

Not 100% sure but suspect it needs a Tech 2 or HP Tuners or EFI Live, in which case it might cost you a licence fee ($100?) plus whatever the shop charges for 5 min?
yeah .. TECH2
most decent repair shops (have to) have it these days
even if only to clear some codes that they have physically fixed
(new sender etc)
the problem here is that it is a custom job.. as the ratio change is not to a factory ratio
so I think it won't be a 5 min correction.
