TMIC swap
BMC drop-ins
Charcoal delete

That's all you really need…

Most other stuff adds heat.

Found some interesting info on ESS' website regarding their OBD2 tune and dyno testing findings:

"*This software is designed to run with OEM S55 air induction system. We have found this overall superior to anything else we have tested on the market. OEM airboxes have virtually 0 restriction and replacing them during our in house testing with an open CAI air intake setup with matched intake funnels yielded absolutely no results at all. We know several companies claim otherwise, but we have not been able to find any advantages to replacing the stock S55 airboxes. Several aftermarket intakes we have seen create MAF turbulence issues and engine operation problems.

**Most aftermarket exhaust systems we have tested on the S55 platform produces less power than the OEM exhaust, the only exhaust we have found to match the OEM in power delivery is Akrapovic."

I've seen YouTube video where they installed different types of intake systems and drop-in + charcoal removal gave the best results on the dyno and drag times.

Interesting info about exhausts systems. However lot of dynes provide better results with DP installed. Curious if they refer to full systems or DPs / Midpipe's / slip-ons?

Most likely slip on.

Downpipes are proven to add power. Midpipes usually add power as well since you are deleting the secondary cats with a midpipe.
