Red and green lines are my last trip at 14psi on 100 octane. Baseline was ~330whp at 14psi after setting up the fuel map for E85.
The next restriction is starting to show itself. The torque is phenomenal but it's dropping off faster at 17psi than it did at 14psi before. I'm thinking cams and headwork are next on the list to prop that up. I also need to get a different boost gauge as well as an EGT sensor, just to see how comically low the EGTs are. I'm expecting ~1300 degrees.
I'm very happy with the results. I would have liked to get more boost but my MBC was acting up and I didn't want to waste time and money futzing with it. As it sits 380whp should be easy at 22-23psi. The torque curve is just phenomenal, essentially peak torque available from 4200rpm to 6200rpm.
Timing is approximately 20 degrees at 17psi. I did a pull at 22 degrees and lost power. 19 degrees was ~345whp.

where did you experience detonation? I like to have at least 4* retard from detonation. I know you hit MBT...but what about headroom from detonation? I vote take at least 4* out considering how we drive these cars.

So I hate you for your early spool and flat torque curve between 4200-6000. You are hitting peak torque 800 rpm before I am. What do you attribute the early spool to? Tuning/fuel map, absurdflowage, IM, VVT, all the above? It does not seem to be the fuel judging by your comparison plot.
