That'd be a nice drag strip setup, but not great for street use. Everything is big
An auto computer actually have a slightly more aggressive tune in them, but if you already have a manual there's not much sense in converting. A combo like that will need an Extender or something of the like, your shift points will definitely be above 6250 revs. I'd almost be willing to bet that a TFS Track Heat intake would be more suited to your combo. Once again, it'll be a topend beast.
