You want to seat the rings as fast as possible and, yes, you want to boost it right away. Use a low gear and drive it up the rev band and then let off the gas and let the weight of the car do the rest of the work. You don't want a steady state; you want variable load. After it's warmed up good, start the boost as soon as possible. You want to load the rings, you see. Don't free rev it and don't think "gentle" with them else you could glaze the cylinders. Change the oil as soon as possible - and use non-detergent oil, or even cheap dyno oil. Don't use synthetic oil at all for the break in period; don't use a synthetic blend. Most people don't even consider the oil used with a break-in and think synthetic and the metal-to-metal contact that must happen briefly with rings and the cylinder walls never takes place and they become glazed. I use this process on my 700plus hp bmw motors and they seat nicely and hold up to hell or high water.
