Forced induction is probably going to be the only way to get significant power gain without an engine swap or a lot of internal engine work! All other stuff will be minimal gains.
CAI= waste of money; tuners= small increase in power, questionable about actual power gain, maybe 10 - 20 %..... just barely enough to maybe let the butt dyno feel a little increase.
Best of luck to you.
Political correctness is a doctrine, fostered by a delusional, illogical minority, and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by its clean end!
