Disconneting Fuel Enrichement Line for MPGs

[Eli]

Same as the 90's Ecodiesel VWs. Disconnecting/Plugging the fuel enrichment line would lead to a turbo diesel with no fuel enrichment under boost.

Thus using less fuel, and getting better mileage.

If this is a viable way to use less fuel. I was thinking of installing a switch to actuate a valve that would block off the line from inside the cabin. So that you could easily disconnect it when on the go for highway use ect.

I am wondering if any of you are tried this and what your results were. I've heard very good things about VW Ecodiesels.

Thanks!
