Do you have to have a tune for the meth injection or does that just make it better?

I have a tune scheduled anyway but curious if it is mandatory for it to function properly.

If you want more hp due to additional fuel ,you need a tune..They can advance timing for hp while meth is spraying. Meth lowers intake temps also..I run ice in my tank sometimes (icy meth good stuff) .you must of missed my post before n/a I gained 17rwhp with meth 50/50
