Interesting, maybe because you tried to reload the same tune again. I just went from 89 to 91 without having to go stock first.

I don't know what kind of tuner he had, but I've reloaded the same tune several times without having to go back to stock on my XCAL-2.

Does reloading the custom tune really do anything? What about disconnecting the battery? Does that clear the computors driving habits curve?

Reloading the tune CAN help but disconnecting the battery for about 20 minutes or more will clear the adaptive learning. You don't need to reload the custom tune when you disconnect the battery. Just be aware that resetting the adaptive learning can sometimes cause some poor idle issues for the first 10-20 miles until the PCM has some data to settle it down.

Hell, I get 19.4 MPG with no mods, no tune. Though I do normally cruise on the highway for about 10 miles at 80mph. Other than that I just drive normally from red lights and never go WOT.
