I ran the Os Xz Speed at this years Florida Winternats, the pipe an header i found to give the best power was the Sirio 2611 with the maxpower header motor clicked off 53mph down back straight.

with 20% without adding 0.1mm shim(hotter engine),that means you ran with richer engine setting,may i know what is the run time for 1 tank of fuel.
