[Vwdiesel] Turbo vs. MPG

[Ron Schroeder]

Hi Mike,

Disabling your turbo will most likely reduce your cruise fuel economy since
the engine will not have as much excess air.  Likewize, disabling the boost
enrichment will only effect full or near full throttle economy.   A little
heavier foot but shifting at lower rpm might help your acceleration fuel
consumption by keeping the engine closer to the low spot on it's bsfc curve.
I have also found 5 to 15% better net fuel economy with propane fumigation.
