I took my first trip since my car received the Eurocharge Tune. I decided to try to get the best gas mileage possible and drove the car at 65mph. My average MPG peaked at 26.5! 70mph was around 25.9 MPG and 80mph around 24.

This was pretty amazing and thought I would share.

Wow this is awesome to hear, and makes me more encouraged to buy a tune. Its weird b/c i recently took a 2500mi road trip in my c55 averaging the best of 24.2 at about 82mph seems the stock tune really is most efficient between 78-84mph ..

Very nice... how's throttle response now?

Quickvr4

Throttle response is perfect, not jerky when cruising but it gives u instant response when you step on the gas. It just wakes the car up and makes it feel how it should have from the factory.

That is some very good MPG for a C55 considering how much they weigh and the massive engine that it houses. Good job

Good stuff! I haven't had a chance to fwy my car since the tune- looks like this tune was a win/win though!!

Are you going off what the car says on the console or actually calculating the MPG for an entire tank? Console will frequently say 26-28-30 when cruising, doesn't mean you get that for any meaningful volume of fuel.

Give it few more days... IT may drop.. I remember I got 28ish mpg after changing my airfilters.. Then the mpg dropped gradually to normal hwy mpg.

I would get 24-25 on a tank before the tune driving hwy late at night w/o ac. I would say 26ish is certainly possible.
