Find a twisty road and run the engine real hard. Use the shift lever on the tranny and keep it in 2d and 3rd mostly and before you go fill up the tank with lots of Techron injection cleaner.
Go out for about 100 miles and drive it like a race car. I think its OK to get it up to the Rev Limiter a few times.
Works for me.
