My dealer recommended no cruise control for the first 500 miles and no towing for the first 1,000. That was it.
Not saying dealers always know their stuff, but that was their answer.
Agreed, fluctuate engine rpm's for first 500 miles, also gradually increase max rpm's so that redline isn't reached until approximately 500 miles. This isn't needed but the dyno results after break in usually yields more HP. I also do the first oil change at 500 miles.
