Recently, I've noticed once boost is up past 3k, it seems power has slightly been reduced. It feels like I'm feathering the gas but it's always WOT. I've been using 92+ octane. The car is 100% unmodified, 25,000 kms (~14k miles). It's being dropped off at the dealership Wed, but would like to get some input as to what may have caused this loss of power.
No codes, no smells....
I also know it's not pyschological (some people say you get used to the power, and crave more lol)
