Gunslinger's Gun Training and Scatter weapons

[Yebng]

If a gunslinger takes Gun Training 1(Blunderbuss) does he get the bonus dex damage when using the scatter quality? The scatter quality specifically states that it "cannot be modified by precision damage or damage-increasing feats" of which, gun training 1 is neither. I'm leaning towards an allow decision but am looking for a consensus.
Thanks

Gun Training actually states that it you select one specific type of firearm (such as an axe musket, blunderbuss, musket or pistol) they gain their dexterity modifer on damage rolls when firing that type of firearm. So according to RAW, blunderbuss' do get the increased damage
