I followed the hard method described in the link (http://www.camaro5.com/forums/showthread.php?t=39955
) when I got my car. Put a dirty side catch can on at around 35 miles and the "clean" side 1LE air oil separator at around 90. Hit 140 before 200 miles on the interstate at 05:30 on a Sunday morning. Oil changed at 1000 miles as well as differential fluid. I have over 5500 miles now and can't keep the grin off my face when guys ask if I have a supercharger because it runs so well and just pulls and pulls and pulls.
Break in your cars however you want to is all I am going to say, but I KNOW how I am going to do it from now on to my new cars.
