I stumbled across this mod( advance exhaust cam 1 tooth) and wondered why there is not more discussion on it. I had some valve noise on my 2009 with just over 7000 miles so I checked clearances and they were all tight. Intake is .004 both, Exhaust is .006,.005. I am waiting for shims. Anyways with the possible gains from advancing exhaust cam, why isn't this a more popular mod? Any and all opinions welcome. OK There is plenty of discussion about this mod here on the forum, just none lately. I'm still new to this (5 months) apologies for my ignorance
