Can you enjoy both power and efficiency ?

[RideOrDie]

This is my first post, I am 19, and I have a desire to learn about cars, how they work, how they don't work, and modifications.
As the title suggests, is it possible to be able to flick a switch and have your car remapped to a set program (saved on a set computer i'm guessing) ?
Take for example, a 2003 BMW E46 319ci, the model lower on power has 118hp, if set up correctly, could you map it to have more than say 150 ? (model higher on power has 143), then have the other setting to focus just on efficiently ?

It's just an idea.
All opinions welcome

cheers for the replies! I am well aware that the key variable is the right foot!
We all know the motor companies are paid off to keep efficiency "low", and we know the easy part is to improve performance. I just think it would be cool to have some sort of contraption that would be like having two ecu's. One that may get you 50+ MPG, and the other may get you some power. Cars use so much technology it must be possible?
What do you think would be best for this, petrol or diesel ?
Do you think it's bad to run lean ?

They are paid off by oil companies so that more oil is used, do you really think they just dont want to start selling a super efficient car, they have the cars already, tyres alone are already made that can double mpg, hydrogen (water) cars etc.
I was also informed by somebody that in my lifetime it'll be illegal to drive cars, they'll be self driven. do ye really think these google cars or whatever they are will be getting "only" 55mpg ?

Now you're talking nonsense. I think it's a more interesting question than some have given you credit for, but you've just wandered off into the realms of nutjob conspiracy.

which part can you not process ?

I'm not here to argue with people who don't accept change for whatever personal reasons. just search "google chauffeur", I know we wont be seeing this anytime soon, but it was launched almost 10 years ago. Whether you chose to believe it or not (not i'm guessing?), the world is moving closer to "driverless" cars. Take for example the 2015 merc s class. pretty much as high end as it gets ? filled with technology that relies less and less on the driver. These technologies will be passed down to the everyday car as time goes on.

and i'm 19 years old, but you do sound more immature not allowing room for a discussion about the future, it's okay tho, we all can't be perfect

Fuel economy will continue to improve as quickly as manufacturers can manage. Self driving cars will be mainstream in 10-20 years. Electric car market penetration will continue to increase. None of this is down to shady conspiracies. Hydrogen fuelled cars look like a dead end at the moment. It's not a particularly convenient technology.

out of interest what do u think will be the best alternative to oil ? my guess is electric.
