Definitive answer on Breaking In
what i did was ran it on non detergent oil from start up to hot and a little cruise around the block. then drained it and changed the oil then beat on it for another 100 miles then ran normal oil. but i did run it na since all my turbo parts were not in order yet, or i would have broken it in on the dyno. so i would do it a little different if i was breaking it in with a turbo on it.
'Beating on it' is not the proper term. Driving it softly will not seat the rings. The proper procedure is to get it on the freeway or other suitable road, put it in 3rd or 4th gear, and run it at about 3/4 throttle from about 2000 rpm to about 75% of redline and then coast, in gear, back down to 2000 rpm. Repeat this several times. There is no 'opinion' on how to do it. This is the proper way if you want to seat the rings correctly. Also, there is absolutely no reason to change the oil after warming it up. If you're concerned change the filter and cut it apart and look for debris. If you find a lot of debris, you've got bigger problems.
To the OP:
I've done what others have done. Rebuild, put in stock ecu and injectors, let it warm up and check for leaks, shut off, trailer to tuner (mine was only 10 miles away), tuner re-checked everything, put in injectors and AEM, slowly ramped up rpms and load, and about 30 minutes into the session he was boosting above 10#'s. 45K miles later it is still hauling my butt to work and back.

This is the only way to PROPERLY seat rings. I do this to all the engines I build. I would say 95% of the time I end up with great results. The other 5% is some other issue that has screwed the rings up, Like washing the cyl's out.
so should i do this "proper" seating of the rings BEFORE i go to the tuner, or AFTER i go, either way the tuner would be doing slow-medium pulls to begin with then slowly move up, wouldn't that be the same as doing this on the highway or suitable road?
If you are having the engine dyno tuned, that should be sufficient for break-in. You don't want to risk washing the cylinder walls or detonating from being untuned anyway so have it tuned first. The rings should be fully seated after your tuning session.
