Yup,thanks!
That run happen along the lines of what I thought has been happening. When I reset the PCM, it allows me to run higher into the power band due to the later shifting. Once the PCM "relearns", it shifts earlier than I want it to. That launch bought me a little bit of time, but notice it just got stronger as it went, putting even more distance from the 1st run. Think that's the best 60' I've had so far, think I normally run around 2.4-2.6.
