I can advance 6 or retard -12.5 crank degrees though I believe I can go up to +12.5. Not sure what that'll do.

Finished most of the tuning this evening. I am going to beat on these maps for a while and see how they turn out, but I am very pleased with the results. The car pulls just as hard as it used to through the midrange, mabye a touch more on the top end, but the low-end is so much better.

With the fuel totally dialed, I think there's a little more power to be had through the torque peak. We may go back later and add a little timing there as well.

KnocksenseMS has been working flawlessly the entire night, BTW.

Pulled a touch of timing in the 5200-5700 range. Got a hint of knock and decided the ramp-up was a little too aggressive.

I am getting shift knock into 5th and 6th from severe boost overshoot, though. In addition, even though I have my map set to 80% DC, it's only reaching 72% DC, which is frustrating. I think I'm going to pull the manifold/DP, drill and safety wire so the damn nuts stop coming off, and port the wastegate all in one shot.
