Just so you know you done need all these mods and gizmos for the half tank lean condition. I found the easiest and most simple fix and it works awsome. Almost to the point to where you dont even notice the problem. Here is my post. Follow this and you will be all set. I have got sooo many great responses from this forum and others about this and wondering why no one thought of this years ago. COme to think of it I have not had anyone say it did not work. Try it and you will like it. It makes the engine run so much better, keeps a tune easier and alot easier to tune from the start.
