Thought I had this sorted out but it doesn't appear so. AFR's still getting leaner towards the top of the rev range. It seems to be worse in higher gears.

I tried locating any vacuum leaks by spraying starter fluid everywhere I could think of on the intake pipes/couplings/throttle body/elbow fittings. Where do you guys most commonly see these leaks? Could it possibly be anything else?
