David,
Since I don't have the 240 anymore, I'll have to let you and the others test these ideas.

That intake tube always appeared to be restrictive to me. I think that another possible problem with it was heat. On my car, it basically laid against the radiator. This new wording should allow moving the tubing off the radiator and insulating it from the heat. I doubt either of these will make a huge increase though.
