After doing more research, i took the plunge and enabled stage 2 without any add-on mods (fully stock). And i have to stay, the power is much more noticeable in sport/sport+. Normal mode, not much difference, bit of more torque. But in sport/sport+ i feel a lot more torque and holding rpm longer before switching gears.
I have to say its not insane amount but for sure noticeable power increase, vey happy with the purchase
