Chirping into 4th.....
My Z barely chirps with a powershift into 3rd, 4th doesn't even come close.
And I have an extra 100 HP &TRQ, and weigh almost 900 lbs lighter than you.
Maybe you got your gear selections wrong?
bwahahaha some people just dont know how to make up stories.
I can see 540i pulling on both of those cars, but when someone post that they chirp in 4th gear, they credability goes down pretty quick.
Unless it is -20 outside and you are running worst 145/70/14, 540 wont chirp.
