Waddup everyone!!! I guess this is the right place to post this.. if not please place it where it needs to be.

So recently I just picked up my motor from the machine shop. It is installed in my car and all wired up and bolted up. Now I have been doing some research about motor break in's.... before I was under the impression that to break in a motor you need to drive like 1000 miles or so... but after all my reading and researching I have seen that there are many many ways to break in the motor. But a common thing I read was that "the main thing to break in a motor is to seat the rings... and you do this by driving in every gear and opening your throttle a certain percent" but since opinions varies so much i have decided to just take it to evans tuning (a local tuner here www.evans-tuning.com) and he does engine break ins so I will have it done there....

now my main concern is when I first start the car.. I understand I have to make sure my air/fuel ratio is at around 14.7 and how critical your air/fuel is... but how do I adjust it? I have a AEM fuel rail and fuel pressure regulator. Do I need a fuel pressure gauge? or one of those air/fuel gauges that go in the car, or a wideband??? and once I read the air/fuel mixture how do I bring it up or down? adjust the Fuel Pressure regulator??? thanks for the help... or if you have any suggestion from engine break ins please let me know
