This is just my 2 cents but ..
I agree we should explore the unknown, but also share what we learn from it. I fell down the 22re rabbit hole long ago. You're still an adjustable cam gear, bored throttle body and supra AFM behind where I was when I finally realized it is what it is. I only mentioned WOT because (on a 22re)it's the top end that suffers most from added air mods(big bores, big valves). The closer you get to WOT, the further you get from the pre-programmed fuel parameters. I hope you get your motor running to your satisfaction, I just thought I'd add some lessons learned to anyone reading this who's thinking about jumping into the hole with us.
..It is a bit surprising that the 261 is so weak off idle, compared to the others.
..As for WOT, in this motor that is open loop, correct? So, with too much flow we are going to lean out the motor, possibly dangerously. ..
Gnarly, Soo... With your motor... What is your plan for figuring out the issues?
Put a pressure gauge on the fuel system first so you don't have to pull things apart.............I think you can tap in on the cold start injector.......

I replaced a fuel pressure regulator on an '85 22re 4runner without removing anything else. I don't remembering it being easy, but it can be done.
I envy you guys with no emissions test
But I love it here Maybe just further up into the mountains where emissions isn't required.
....I'd consider moving there but the beer situation would be upsetting.
.... Currently I am happy with the OS valves and open exhaust and I will never take that any further.
