I have found that if you set the properties up in the tuning software to retain crank data and do a full read and copy to the road runner you are bretty good to go.
You really only need to do crank relearn when your using another base tune on a different engine.
Keep an eye on your vin number when pulling from a USA PCM, I have found there is a few strange things going on.

Holden guys, Crank relearn is not needed. It's only used for misfire diagnostics, thankfully Holden never turned those on with the LS1.
Cheers,
