I've got about 35p miles and 17.3 hours on my 858. Yesterday was the first ride after getting the re-flash done. Night and day difference. Before it would bog and sputter between 30-40 mph like crazy. If you tried to 3/4 pin it, it would most likely not be there all the way. Now it's smooth and rips like it should. Same plugs but have thought about changing them out because of the break in. Dealer said break in was 500-1000 miles wtf
