Hmm, just to remove any doubts:
LV78 Mega Charizard X (240 Attack) uses Fly vs. LV100 Aegislash (147 Defense).
If 1.2x boost, Fly should do 50-59 damage
If 1.3x boost, Fly should do 54-64 damage
First test did 56 damage. Second test did 65 damage. That's... odd. Perhaps there was a problem with my math?
((((78*2/5+2)/50)*240*90*1.3/147)+2)*0.5*0.85 = 54.8
((((78*2/5+2)/50)*240*90*1.3/147)+2)*0.5 = 64.4
Now, we could attribute this to some sort of rounding error, but there's another possible explanation:
((((78*2/5+2)/50)*240*90*1.33/147)+2)*0.5*0.85 = 56.0
((((78*2/5+2)/50)*240*90*1.33/147)+2)*0.5 = 65.9
Based on this, I believe Tough Claws has a x1.33 boost.
