Tooter manifold / Corolla TB / DC Header / etc....

I would say that IS likely the problem. 142 F is still well within the pre-warmed-up temperature range.

It was 55F here this morning when I drove my kids less than 2 miles to the camp bus and by the end of mile 1 (mostly downhill) I was at 181F.

Next step = remove the colder thermostat - take some driving impressions and datalog the info.

It won't be 8 months (or never) ala "something big is coming", but it will have to wait till Friday night or the weekend because I'm busy tonight and tomorrow night.

Then, after the thermostat, if there isn't an improvement - the next thing will be to remove the Corolla TB (swap back to Stock tb on the Tooter) / then I guess the next thing after that will be the Factory Manifold etc...etc......

Only good thing about this process is that now I've done each part so recently that they stick in memory and therefore are pretty quick and easy to swap.

That's the prime directive for modern vehicle engines. Super quick warm up to operating temperature so as to meet government mandated emissions requirements. In warm California, my green light goes out before I get to the end of the driveway.
