Want more reliable power

[Stingerguy818]

Hey guys I have a 18 gt2 awd with intakes, jb4, mbrp catback and ark downpipes, hks m45il plugs, oil catch can, I think that’s about it. What can I do to make some more power or maybe run like e50? I run e30 with my jb4 currently am I damaging my car at all or am I fine? Just want to hear suggestion on how to make some more hp thanks. I’m in California only have access to 91 and e85
