At what point does the engine begin to show loss of HP.

I noticed that during winter the car seems less peppy even in sports mode, so not sure if that's attributed to weather or engine finally 'settling' after being run for a year.

I want to install Mppk but figuring out if I should wait till spring or not bother at all at this point due to age of engine. 8k doesn't seem like a lot of miles but just asking.
It's my understanding the colder weather allows your engine to make more power.
From what I've read (magazine tests) engines need to break in and perform better after a few thousand miles)
Are you driving it more conservatively because of weather?
