Set boost at maximum, nail throttle, throw up clutch, enjoy! Itll blow up in 15000 miles anyway so you might as well enjoy it

As Simon said. Load it up as often as you can. Find a series of nice long hills to drive up and down and cruise up and down them on part throttle, just enough to build a small amount of boost. Also a few squirts at 0:80 bar boot will do it good as the boost helps to push the rings into the bores.

I did 50 miles just plodding around on mineral oil. Then changed it and done another 250 miles on mineral oil driving with the above method. Then changed oil again for Fuchs pro s 10/50 and drove to indigo about another 50 miles later for mapping on standard vii turbo running 1:70 bar before swapping to S205 about 1500 miles later @ 2:00 bar :)

That engine is still alive today about another 20,000 miles later and is used in a tracked Evo IV with a Evo IX turbo and the owner says it don't burn a drop of oil :)

Interesting read as I will be running in my forge engine in a week or two. I was advised 500 miles of normal driving then she'll be in for mapping. I read somewhere someone ran it in on a tank of fuel then mapped it and had no problems.

Some big names over the road run them in 50 miles then map them with no problems, I am a big believer in this method yet if it was my own car I would be a bit more timid in running in
