I would guess that along with the improvement wrought by the M7 ported s/c, there might be gains by leaning out the JCW program's a/f numbers. Just a guess. Anyone know for sure?

Spider you are correct . We changed the JCW pulley out for the 16% M7, added the M7 ported SC and the Mth software remap.

That particular car dynoed recently at 197 whp.We were not present at the test and i just read about it on our local forum. I do not know what other changes, if any, have been made to get there. You will find that as far as dyno results go the Mini's vary from one car to the other a considerable amount. We have seen a bad JCW and a good stock s dyno within 3 whp of each other on the same day. There is no figuring it .Your results can and WILL vary
