Re: MAF and TB cleaned, MPG rises, 0-60 unchanged.
Have you accounted for any difference in tire size in you mpg calculations? I think that may have more of an effect than the weight difference in you tires.
I did not read the 0-60 time link that you provided, who did the tests? If it was Toyota, these were probably done with a staff of engineers present to make sure that all conditions were perfect, on a new vehicle. If the Tundra was rated at 8-9 seconds, and you are at 9, some would say you are already at the 'production level' in a 15 year old, 150,000 mile truck. Not bad.
Going from 9.2 to 9.0 is about a 2.2% decrease in your 0-60 time. From an engineering perspective, that is not really all that bad, with the limited mods / maintenance you have done.
