I am a little confused aswell! can you just get a custom tune to improve economy and power without purchasing  a flash box?

<{POST_SNAPBACK}>

In short - Nope.

There are two mechanisms for tuning these cars - the piggy back or the ford flasher box (=edit).

Your fuel economy should improve marginally if tuned for this (perhaps 5 - 10% dependant on what else you do), but I would not expect any huge gains - the best way to improve fuel economy is change the way you drive - or in an extreme sense - remove power boost and available rpm to decrease your ability to drive in a manner that consumes more fuel - but then what is the point.

My 2 c.

Cheers,

Ben.

I am not after better fuel economy as I am getting better economy than my old v6 vx wagon and happy with that just wanted to know the situation in regards to the flash boxes as I always thought that if you want more power you wont get it without using more fuel. cheers

That's correct to a point.

If you use all of that extra power you will use more fuel, but in just "normal" driving you should use less fuel.
