thanks to Mike Litch @ Tech Support
He updated my last written tune in 9r12 with throttle boost 20%. WooHoo!
Luv the service mate!
cheers

The crom v9r28l updates my predator fine-ok.
Connect predator to 2006 300C 5.7l export model and message displayed
"v9r28l does not support this vehicle CAL ID"

Guess I'll have to revert to v9r12 unless someone can offer work around for me.
cheers

Thanks Mike. I also had problem with "missing serial flash" message on predator. Will try this 9r28 lite version
