Upgrading 528i
I have a 2016 528i xDrive (n20 engine), I was looking to go to stage 1 or even stage 2 right away, is there anything I have to be careful on? Im pretty sure the timing chain is fixed on the newer models, and I already ordered a charge pipe because those are known to go, but is there anything I have to worry about? Just got the car about 2 weeks ago so I dont know too much about the reliability, ect.
