I will say the car improved over the first week or so with driving. It's also an adjustment period in your own brain, it's not like upgrading a turbo car where you get new software and there's a huge whack of torque now with more boost.
What I noticed is that as I drove the car in normal situations like my commute, it "surprised" me as I wasn't thinking of the tune/upgrade/3SI, just making my normal drive.
Second - the engine "breathes" above 4500 rpm way better than before, that's where if you (once warmed up of course) run it through the gears, the HP is quite apparent. That along with healthy torque bumps in the 2K-3K range, and 3K-4K range.
What I definitely notice is the DISA "transitions' at 3K and 4K, where you get torque "Dips".
Long story short, reset adaptations, drive the car a few days and you'll notice the power, it's quite apparent.
