TT46
If you read your manual that comes with all TT eng. it warns against Fox plugs. I use OS A3 or K&b 1L with great results. None of my TT's will run on the miracle plug.
And don't worry about what anothers settings are, even if the same eng. Counting turns will get you in the ball park, thats it. Then you'll have to dial it in with experience.
