Got a Tyranitar from a raid

No, evolve a 100 IV and change the moves if you want.

Congrats and great moveset! If it's hard for you to come by TTar and you can power one up to be effective by all means! If you are okay on attackers, you could afford to wait, and potentially get a better one off of another raid!

I am still using rare candies on lavitar to just get my first one..... Lucky son of a gun! Haven't even seen a Ttar raid.

I would not power that thing up.

I would stick it in a corner somewhere or use it as a gym stuffer until the system changes.

Don't waste your candy, better ones will come along.

Got a Lapras raid yesterday, congrats on the rare raid! I got a FB/IB one with fantastic IVs too. The ATK IV is a bit low for my preferences, but if farming candies takes too long, I'd say stick with it since your moveset is ideal for attacking gyms.=3

The new update has certainly gave me a dilemma regarding my 100% Larvitar. Do I continue working towards the required candy to evolve or do I just use a TM on my current IT/FB Tyranitar?
Feel's like rolling with the TM's is probably the most logical choice, it would save many candies.
