Same mods on mine, other than 1 3/4 headers instead and that my car was completely heat soaked on a 96* ambient day and made 424/442 for reference.
Id expect closer to your numbers if it were cooler.
That's pretty good. My 11 GS M6 made 432/424 with the stock airbox, kinda curious to see if it picks anything up when I get around to doing an intake. It was dynoed in south florida so probably would have made a little more in better air.
Damn I feel Ive wasted money.
My 2011 with a small cam, 1 3/4 catted Kooks, and vararam made 446/442 on a dyno jet. It made 465/442 with a btr 2 cam but I went with something a bit more streetable. Maybe it’s cause I have 1 3/4 headers and not catless.
I will be doing a cam here soon, specs are 235* of intake duration and 243* of exhaust duration, .621" of intake lift and .624" of exhaust lift (1.7 ratio), and 113* lobe separation angle with 3* of advance Ill post an update when its all together

Numbers are just numbers. Comparing dynos is like comparing insurance rates.
