It seems my rear brakes aren't working that well. Missing breaking power and car tends to dip more.

Anyone experienced this before?
I am using mintex reds on stock rotors.
Was working well the first 5K or so.

Well, technically, you don't even NEED rear brakes...how do you know it's the rears?

Default Hey Liam, I got a Q for you re: K04

Do you run less boost when it gets cold? I notice that on my car, I run only 12-13 psi when it's cold out compared to almost 18 psi during the summer. Is boost cut back as dramatically in the K04 software? Thanks a bunch.

Default less boost for sure...not sure how much though

I think 13-15 is about right.... it's been warmer these past few days, so it's been a little higher

I don't check the boost much anymore when driving around the city. I have different driving "settings" ...

grand ma setting: 5psi throttle (also known as fuel-saver setting)
normal city setting: 10psi throttle
ticket-o-matic setting: wot

Default its a direct transplant. get used S4 caliper/bracket from salvage store, i also used used rotors

and it felt great. now i have new A8 slotted rotors/brackets - slightly bigger but feels the same as the S4s. i will probably switch to S4 rotors for track
