Default Break in Before ECU Upgrade
What is the current thinking about waiting on a new car to a certain point before flashing and a pulley upgrade? Have a new car coming and want to do it, just wondering if I should wait until a number of miles first.

I would definitely complete the 1000 mile break in before modding it.

Most major engine defect failures happen at below 1500 miles, but I waited till 4300 miles to tune.

ECU upgrade. Is it worth it? Any regrets?

Just broke 4000 miles on my 3.0, and have to play devil's advocate to the urban legend...
