Timing dips really low, and there is a lot of timing being pulled at lower RPM. It doesn't seem very happy.
I dunno, that map looks like it is running like junk on your car overall. What map is this? You might try finding someone to custom tune your car.
Are you actually getting a CEL? Or does it just flash when this happens then go away? If it just flashes but doesn't actually leave a CEL, that's misfire. It can be caused by lots of things, but checking your plugs would be a good start.
It could be the map is running way too lean causing misfires. Usually the front stock O2 sensor will go right down to 0.72 in boost because it was not made to read correctly under boost. Yours is not doing this, which kinda makes me think you're running way lean. You really need a wideband to tune fueling.
