Okay, Here's the report on the test run. The vehicle is a light crew cab pickup. The trip was from Kalapana to Kona. AC on all the way.
1. MPG: He says he's never gotten more than 23 mpg before and on this trip he got 27.4 mpg. Carefully checked.
2. The engine showed improved power. Not massively but just some stronger on the hills.
3. The engine ran so quietly he couldn't hear it at times.
4. Nose to the tailpipe he cannot smell petroleum fumes at all.
5. Engine ran smoother, no pings or valve chatter.
He is happy and says he would make this modification even without improved gas milage.
I asked him about engine temperature. He didn't notice any rise but wasn't looking. He'll pay more attention to it tomorrow.

Assume the best and ask questions.
