Best device is your right foot...
And by reducing fuel mixture (lean) MIGHT cause damage to the engine in the long run if you like to high rev. not to mention lost of power as well...
Suggestion is to get your AFR to STOICH and control your right foot

But then I have already train my right foot not to rev very high. Almost always I will shift before 3k rpm. But the FC still seems quite high. Not carrying any weight also(single driver always). I thought maybe can further reduce down the FC.
