You mean the E-spec? YES it is considerably faster, even more so than OS claims. Fast enough your lap times will probably decrease!! LOL J/K. But very serious about the power.
Bottom line about engine break-in guys. I posted on this many pages back- you can search for the details, but a fresh engine DOES NOT need tank after tank of idle speed with a rich setting!! All you have to do is run the motor conservatively on the tune around the track the same way you would race- part throttle, sometimes WOT, etc. Just don't run but 2-4 minutes at a time. Let the motor cool then run it again. After 3-4 heat cycles start sneaking up on a good tune and roll.
HEAR this- idling these motors super rich over and over and over is killing the piston to cylinder wall seal!!! You are washing the freaking cylinder wall down with super rich settings!!
