I'd always recommend a retune after adding meth, but it really depends on what you want from it. You'd need a retune to add the additional power it would allow you. You might be able to get away with not retuning it if you're just using it to increase octane for safety, and not adding any more timing. That being said, I'd always retune after adding something like meth on a FI car.
