plug diagnosis

[slow poke]

New tr6s, 30-40 miles on plugs, no full throttle running or taken above 4000rpm because i am self tunning. AFR never seems to drop and stays around 14-15s.

Do the plugs appropriate for what is stated above?

Yes.

part throttle cruising will show air fuels in the 14's that is fine..
