I agree with you. I haven't updated my thread lately but I ended up buying Wiseco and Eagle combination just to be safe since I will be running GT2860rs and running high boost on track days.
This one Z recently spun a bearing at 600hp on stock TT motor with GT2860s and e85 tune. I guess all engines are different but that's impressive power out of stock motor with only bolt-on upgrades. I would say 500-550whp is pushing the stock motor.
