Phone [Q] Amazon App Store - Other device specific mods on a newly CMed KF2?

I have a Kindle Fire 2 KF2 just flashed it from stock to CM11-201403-SNAPSHOT-M4 Stable
When I side load the current Amazon App store is close flashing a message "Unfortunately the Amazon App store has closed"
I changed the build prop to for the vendor from Amazon to Asus and rebooted (did not change the model number) I used the guide here

Are there any other KF2 Device specific mods I need to know about Playstore, BBCiPlayer etc all seem to work fine.
