I meant to tell you in the Ninetales thread, but didn't get around to it: your speed EVs are surplus. You outrun Jolly Mamoswine, but you have a bit of extra speed you aren't using for anything. The EV spread I suggested was a mirror of the set you were using as I posted (I think?), but with the 120 EVs from Sp. Def placed into Defense instead. If you're only trying to outrun Jolly Mamo, you should be using 252 HP/160 Def/92 Speed, which hits 286 speed to Mamo's 284.
