Just to summarize, the pipe for it is the Go efra 2072 pipe w/manifold. P3 OS plug.
while breaking in add the extra shim, after break in change rod, and run .4mm shimming (remove the extra shim).

"Heat cycling" method is the way to go, mine seems to be almost fully broken in, and it has run about 3/4ths of a gallon.

For the price, it's great.
