That looks sketchy. The car is spiking a huge amount of boost in the midrange. I would say a dangerous amount with 91 octane and the car's computer agrees as it's pulling mega timing and closing the throttle plate. Minor timing corrections in a few cylinders are fine but you are getting timing pulled everywhere and timing is actually retarded (after TDC) in cyl1 until 5200 RPM. That sounds like a recipe for disaster with really high EGT. Your IC does look like it's working much better than the stock unit, since it's clearly very hot there.

For future reference, it will make it easier for people to review your logs at a glance if you tick some basic parameters like all the timing corrections, boost specified and actual, timing cyl 1, throttle position.

Flashed back to Stage 1 from 1+, looks like it's still acting wonky.

Any ideas of what would cause this?
