fuel economy drop with turbo tuner.

Ive had it for like 5 days and the fuel aconomy has dipped fast.Granted I have been driving it hard but it went from 19.9 to 19.3 already.It seems like it might get worse.What is everyone else getting.Im curious as to what it will get driving like a civilized human being.Oh well, its very,very fun though.

well if your flooring it since you got it that is the reason...but .5 mile difference is nothing to be worried about... specially if you are really flooring it a lot.

Takes fuel to make power. I am only getting 14.1mpg so far on my stock 335i in 1600 miles of driving.

Last tank of gas I drove my stock 2007 335i the exact same way as my 1995 540i (w/ dinan chip). The daily route I take is 15% city 85% hwy. So for over 300mi, I get exactly 1 extra mile per gallon 23mpg w/ 335i vs 22mpg w/ 540i. After some break-in time the fuel economy may improve slightly.

To run more boost, you need to use more fuel. You can't have your cake and eat it too.

It really depends on the load. Some Turbo Tuner customers have gotten better gas mileage as well and that's only obvious if they're not always doing WOT runs.

Same can be true with the piggyback units.

That's while cruising, not WOT. There is no extra boost when the car is in vac.

The TT shouldn't increase your gas mileage, it only takes effect under boost. The procede/xede can lean the car out during part throttle for slightly better gas mileage.

As stated above:
"The procede/xede can lean the car out during part throttle for slightly better gas mileage."

FI cars are usualy tuned rich form the factory for an extra margin of safety, so that's an easy place to look for performance. The fringe benefit is that this also improves fuel efficiency.
