Foolish of me....
 

It occurred to me...

Has anyone owning a CX-7 already wired the wastegate open to see what the resulting FE improvement might be/is....

I know that this would result in a significant reduction in the power band but for constant speed, relatively constant speed, highway cruising it wouldn't be so noticeable.

If simply wiring the wastgate open does improve highway cruising FE somewhat then I would better know whether or not it would be worthwhile to purchase a CX-7 for an FE improvement, maybe 50%, experiment.
