I really wonder why the Escalade V doesn’t do this? Same engine and makes more power so it definitely needs a break in but they don’t even include anything talking about break in.

Mean sounding blacking

Sorry, you probably should have read the owners manual. Recommended break in is 1500 miles in which not to exceed 4000 RPM, 80 mph, and avoid full throttle starts. I guess if your LT4 blows you'll have to argue that it's Cadillac's fault for allowing more than 4000 RPM after 500 miles. So they're not clear on what is really allowed/expected. Warranty states voided if "not following recommended guidelines." Probably need a lawyer to argue that one. If anyone knows the real story, please post. Otherwise I'm afraid others might follow suit. I'm at 900 miles on my 2024 and it's killing me to keep it reigned in.

Must be a car guy thing, no idea what I just watched

It was the longest mile.. Worse is the diff is supposed to be 1500 miles. I took mine on a business trip and dropped 800mi on it to get over the hump.

Does the ECU allow more boost in higher gears?

6MT？
