The days of disabling the EGR system to increase performance ended approximately 40 years ago.
Modern engines have a finely tuned smart EGR system that’s required for proper combustion . Proper combustion on this engine and all modern engines is dependent on EGR dilution.
Also, EGR will lower the combustion temperature which is what you want with turbo boosted engines.
From hindsight, if you’re planning on keeping your vehicle for a really long time, buy 2 more EGR valves now. Or three.
Don’t wait a decade.
Emissions components are one of the first things that Toyota discontinues when they start discontinuing stuff, and the EGR valves are wear items. They definitely don’t last forever.

Why not try unplugging it? I would contact a tuner as well. Assuming you live in a country that does not require emissions testing.
I understand what the guy is saying above about technology but still wouldn’t force someone to eat some of their own s*** every day.

I had my FJA300 delivered a couple of weeks ago, finally. I dropped the thinners they call oil in the AU market (0w20) on day one and changed for a 5w40. Where I live it never gets less than 10 celcius. At 500 miles I had the DPF (and the rest of the exhaust inc catalyst) removed and the EGR deleted in software. Fitted a 3.5" turbo back system with a single muffler. Tuner has dropped the AFR from ~18 down to a squeak under 15, and raised peak boost to 30psi. I'm only at 800 miles now, but economy seems better and it has a sense of urgency one wouldn't expect of a landcruiser. Peak power up 30% and torque 15% at the wheels. I don't drive this vehicle hard, but it will see heavy towing duty, so I'll uprate the chargecooling in due course. Warranty: ZFG.
