Anyone had success with G3 lem on F20c?

[Glenn]

just curious as to whether or not going to the G3 lem would acutally be an improvement on an otherwise std f20c engine- any thoughts?

[Simon]

It really comes down to how well the factory system is doing its job. On a totally untouched engine the gains would be small if any. However if intakes, exhaust internals are changed then that is another story.
