Recalibration
Bout 2 put my new diff with set of gears in. What have people done 2 recalibrate the speedo ??
When I die, I want to go peacefully like my Grandfather did, in his sleep -- not screaming, like the passengers in his car

VY is simple get the dash reprogrammed with the correct PPK for the new diff ratio.
a holden dealer can do this using a Tech2
I work at a holden dealer and yes its just a simple reprograming with tech 2. wat diff gears r u gettin cause some ratios wont match the different options u can choose from

you dont need to stick to the PPK values in SIP
you just need to calculate the PPK
original PPK / original ratio
then multiply the result by the new ratio
program the new PPK.
or check the speed with a GPS & calculate it that way

i didnt bother recalibrating, mine was about 20km off with 3.9s
