i ran mine on a Friday test day for about 3 sessions then loaded it up and took it home and changed the oil then took it to the dyno and made about 6 pulls. ran it easy in sat morning practice and qual and short shifted it for the races that day. i didnt baby it other than just short shifting. get as many cold to 180-200 degree heat cycles on it as you can before you run it on track.

the 98 Camaro i had was broke in on the dyno. 26 miles of cyclic rpms and then we made about 100+ full throdle pulls over the next two days dyno tuning it. the thing ran like a top for many years.

the fact that it seems everyone does it different tells me there is no real right way. i've always leaned towards "break it in like your gonna drive it".
