Take a quick look at your A/F ratio and its around 16 which is even lean for cruising, let alone peak tq.
That thing needs fuel, in a big way. I would seriously not even drive your car at WOT until you get it back on the dyno with some added fuel (or pulled timing)
You'll want to see that AF around 11.5 on pump gas (not sure what octane you're on) but anything from the pump needs to be around 11.5
It even appears you're lean through damn near all of your powerband

Welcome to DI. These cars all run ugly lean. The drop has to do with boost overshooting the max and the car compensating for it.
