so should i get a FMI or will methanol work better?
Both.
I have both to be honest in 90+ weather I still get heatsoak.
Well, I think it's heatsoak, I have a hairline fracture in the stock mani, so it may be getting hot and leaking, and that may be what I'm perceiving as heatsoak, but I dunno, I don't think that's it.
It looks like you already have a Perrin FMIC though.
