Turn boost down. Keep it under 3K, rpm for the first 200miles. The more start and stops the better, highway miles do not count. Then slowly start getting higher rpm. Wait about 500 miles minimum before going full crazy.

I did same procedure except 600 miles before going crazy. Wanted to give myself a little buffer for my own peace of mind

I did a break in of 500 miles, mix of city(mostly)/highway. Plenty of starts and stops, like stated above, the more the better. Want to get plenty of heat cycles through. Keep out of boost and keep it low rpm for sure.

Im 36k on my mfactory smfw and spec 3+ as well and seems to be holding strong for now.

Is breaking in a new clutch a thing?

500 miles of city driving seems excessive
