Choice scarf

Answer 1

Timid no investment Charizard lvl 50 - 132 speed
Timid 252 speed Charizard lvl 50- 167
+speed nature 252 speed Torterra lvl 50-118

So it is very likely scarfed as it would boost Torterra to 177 speed outspeeding Charizard. Also Rock Polish could have been used to make him 236 speed.
