I am pretty sure the tuner has come loose. Noticed my RPM's just a touch lower usually can do a pretty easy 5600rpm could only manage about 5450 or so. With this cold front should have been no problem.
So my question to the experts, do you think tuner also, if so i realize the power head will need to come off.
Do i just need the base gasket, tuner gasket and some red locktight?? any thing else i should do or tips?
Here is a vid of the sound.
