So, if we believe their dynos, and you want to get 3% more hp in the upper rev ranges, why not just drive at 3% higher rpm? That is free. To me, none of those very minor hp gains mean anything on the street unless you are at WOT, preferably at redline. My X5 never spent much time in that situation.
