| So far only about 60 miles, But I think I have a decent method - a hybrid - of general break-in logic: Idle and slowly increase neutral rev's to 3k-ish for 30 mins, changed oil. Then drive, no more than 4k rpm regularly, 4.5k occasionally. Lots of engine breaking down hill in low gears (get that vaccuum up high!!!). After I give the first 100 miles and change oil, I will gradually start boosting more. For first 1/4 of break in I generally avoid prolonged boost and certainly keep under 5psi. Oil is conventional (Rotella T - for detergent/heavy wear factor). That's just how I do it. Anyone can feel free to expand/criticize. I find first 100 miles is quite critical, but all the best to avoid undue stress on the bearings, easy on the boost, but a high priority on getting those rings to seal!!!
