Turbo Boost vs MPG

Hello everyone,

I had a thought the other day.

When I first drove my 300D 2.5 home from Columbus. It got 39MPG.
This number is high from what I've heard for a 300D 2.5.

As I worked on the car, I am now realizing the turbo is not actually doing anything. No boost. The car is still drive-able, just slow. 0-60 is 20 seconds. Even slower when the governor kicked out and I was stuck driving in second gear. A 240D would have beat me!

This got me thinking.

If my 300D can get HIGH 30s with no boost, and (presumably from everyone else's numbers LOW 30s with boost..

I only really need boost at certain times. Maybe I can get the best of both worlds.. I could employ some type of electronic wastegate controller...

What do you guys think? Or is my reasoning here flawed? Was my 39MPG a fluke, now given that the turbo was NA?
