Well, from my first round of testing it appears that my car likes 100% meth better than 50/50 -- I was able to run more boost and timing with 100% meth. I have made some more changes to my tune and will log later today, but my guess from the first round of tests are that: (1) I need to decrease timing still, (2) richen my AFRs a tad (in spots I was at 11.5 - 11.7 which I thought would have been great), and (3) play with VVT.

I wonder what that means: (1) my intake charges need the additional cooling, (2) 91 is just too prone to pressure pre-ignition, or (3) my cylinder walls were really not that hot ??

Evan -- Thanks a ton, for helping. The jet is on the bottom side of the UICP, so it is really hard to see in a picture. That said, the jet is ~3.75" from the 90* silicone elbow that connects to the throttle body. So the jet is probably ~7-8" from the throttle body.
