I have stock everything but the flash tune on 93 octane and it's pretty fast. I'm pretty sure the concessus on filters for this car is they are mainly for sound and MIGHT help performance a little. It's just $50 or so so really it wouldn't hurt to get it but it's not required.

That's with just the tune, short shifter, RMM, and I took out the spare tire and jack.
I've actually gotten faster since that video. With some more practice and maybe lowering the psi in the front tires I could get under 6 seconds.
