Best way to create more power after intake+jb4?

[cLaw]

My next mod will probably be a catback exh, but is there anything else you can add on map2 of a jb4 to create more power? I do not have e85 anywhere near me so the only option I'd have to get a higher octane would probably be WMI but I'm not fully ready for that at the moment. I've seen so much discourse on here about down/mid pipes making no difference at all to people saying it increases power by a lot. These discussions were mostly from 2019 so is there any new info or testing thats been done to prove otherwise? Just looking for the next best thing to go for performance wise without investing in WMI.

Weight reduction, (lightweight wheels, lithium battery, carbon rotors) shorter gears or final drive

You might be able to get a little more power with a dedicated ECU tune. The internal maps and timing are pretty conservative. The jb4 can only fake the ECU into thinking it has less boost than it actually does. It can't do anything to optimize timing and other parameters. A dedicated ECU tune can do much more.
There is a fairly new platform, the EK1 from Sxth Element. This allows you to unlock the ECU and flash tunes directly through your OBDII port, no need to send it in.
See this thread.
Currently they offer a Stage 1 which works with 91 or 93 octane and intakes, or a stage 2 using 93 and high flow midpipes.

TCU from Lap3 or Lozic. It won't make "more" power, but it will allow you to more effectively use the power you have.

If you’re not ready for WMI then you should just stop chasing for power. You just simply can’t push the car that hard without sufficient octane level.

Try TCU or simply a brake snip harness, that will help launch way quicker than before.

Yea this is what I figured, just wanted to double check before making any other decisions
