Pete - I have offered to prove it to you but you haven't got the ***** to accept. I know the facts because I not only have twice the power the subaru engineers deemed suitable for my car when i need/want it but also much better fuel consumption that their mappers thought to do.
Unsubscribed now.

I know you consider that you are better able to map a car than the Engineers/Scientists and Designers at Subaru ...... you could be right.
But, if it was possible to get 550 BHP and 30 mpg - as I have said numerous times - Subaru would have probably stumbled upon it by now ..... don't you think?
What amazes me is that not one mapper wants to say what the downsides are of a re-map ...... just the cost is what is offered. Which doesn't add up as the cost of a map is not an issue for Subaru ...... it is already factored in.
Have you thought about offering your map to Subaru? I am sure they would make you a very rich man ..... imagine the Sales which would result in selling a 550 BHP Impreza which also returned 30 mpg - they would take the market by storm!

At least now Pete can agree with his own theories/fantasies/urban legends, I suppose it gives him new areas to explore in the very recesses of his own mind.
So then is it split personality syndrome that you suffer from?

At least dynamix and other mappers have fought their corner with dignity and pride.
You, Cannon Fodder, have simply chipped away with personal insults .... adding a big fat ZERO to the debate.

Sorry SSU/pslewis I have not meant to insult by intention but if I have then I apologise. I merely thought you enjoyed banter after you have used it so often.
When I started posting on this thread I posted my contributions you mocked me and intimated that I practically did not have a clue what I was on about!
I find it confusing that you have disputed posts by mapping experts, claimed that they have a vested interest and then just continued on unabaited.
Many members myself included can see the beneficial byproduct that a remap provides ie fuel burnt more efficiently equals better fuel economy when not driven with bravado. . But even a standard Subaru map will use more fuel when driven hard.
I will tell you what my car is going back up to Bob Rawle in a couple of months after some further modifications have been carried out, come along and if a remap on even your standard engine does not increase the fuel economy of your car then I will offer you a public apology on this subject.

If a re-map on my car increases the mpg then it will be running lean - not so long ago running lean was seen as a very bad thing indeed .... now, it seems to be a virtue?
And, of course I enjoy the banter - I got a response, didn't I?
That said, I firmly believe that Subaru would do what the mappers do - if there were no downsides ................. there clearly are major disadvantages to doing it - but what are they?

It is not totally out of the question, though. Mitsubishi brought out the 400bhp Evo9 with a 3 year warranty. If you look at the official economy figures, there is not much difference between the FQ300,320,340,360 or 400.
In fact the 320 and 340 are more economical than the 300 according to the govt figures.

Can one of our resident mappers please give Pete a map on a "like it or your money back" basis?
I just know he'd love it if the "old codger" wagon got some Sanatogen and Viagra shoved up it's tail pipe and would be a convert to the wonderful world of Subaru tuning
To be honest I've not properly measured my MPG Don't have the heart: even std Subarus vacillate between "Below average" and "George Best"
Suspect MPG better on cruise and off boost and worse when I use the loud pedal....no surprises there then. What I am Certain of is that 350bhp in a classic don't half feel good and that my Scooby hasn't put a foot wrong in five and a bit years!

I don't want my engine blowing apart ... I mean she has got through 99,000 miles with the gentle caressing of my right foot.
An old experienced driver at the helm is probably worth 50 BHP on its own? maybe even more? You kiddies need the extra, I just drive properly
I could start giving lessons ... would be damned cheaper than a re-map ... yet deliver you to the end of a run faster than some kiddie with a few BHP more!!
In line with the current re-map thinking ... there would be a ZERO Warranty

Much the same thinking with the young uns, except they're more likely to expire in the car!

Generally, a remap will make the engine run more efficiently and hence more reliable, but this will be offset by the extra strain on the components due to the extra power. So it is impossible to say as you would have to get 2 identical engines, remap one, then drive them identically until destruction.
On the subject of mpg. You argue that more power must need more fuel. On the F1 practice today, a Cosworth engineer stated that a F1 engine is so efficient, that if you put it in a Toyota Prius, it would be more economical than the hybrid engine it has. Put that in your pipe and smoke it!
The reason F1 cars use a lot of fuel is due to the aerodynamics required for downforce.

Pete, i'll have some lessons! You a trained driving instructor to RoSPA level? I'll have some of that. Otherwise, I feel you are trained to 'nip to the shop' level ya old codger. LOL

I don't need Mickey Mouse dials to tell me what's happening .... at my age I am at one, in tune, with the vehicle I am driving.
Like I said, my skills and experience must be worth 50 BHP over some kiddie who needs boost gauges and cocklinks to drive properly!

When you modify a car its for a particular need - any car is a compromise.
But you and the other stirrers cannot separate 2 simple ideas - you keep lumping them together to promote argument - so sad !
A 550BHP car has the option to go very quickly with very poor economy, OR at the same speed as a 250BHP car with BETTER economy. I do not for one second think that anyone believes that you can use 550BHP AND get better overall economy than a 250BHP car. But at least you have the choice of poor mpg fun, or drive it at the same speeds as a std car with improved economy.

I have been driving high performance cars since the 60's and still feel uneasy without some essential monitoring (even you probably have a water temp gauge - unless you disconnected it to save energy !)
You are confusing knowing how your engine is performing with driving skills - again, 2 separate issues - but when lumped together promote further pointless argument. So sad !

I thought the issue was whether a remap improved your mpg, not that it was harmful to your engine.

Man and machine in perfect disharmony - the car thinking "I wish he open me up now and again" and Pete thinking "I'd better not stress the engine by going above 3,000rpm".

If what you state is true, that is:- you can have a 550 BHP car and do 9 mpg (say) at WOT ...... but, can drive 'sensibly' and return around 30 mpg. WHY, oh WHY, do Subaru not offer that option (wouldn't be expensive for FUJI Heavy Industries to do that).
Of course they would offer a 550 BHP 30 mpg car in their range of offerings ..... they don't!

Because the 550 BHP car would cost a fortune to build, have less reliability (mechanically), be impossible for most drivers to drive safely therefore not a good spec for huge sales. They have to appeal to a wide audience ! So they offer a car which is a good "allrounder" but with potential to win rallies if additional money is spent. People who want a choice of high power with poor economy (when the high power is used) and better economy with th esame performance as a standard car can chose to spend extra money to achieve this.

i would say it's the 19,000rpm it is being driven at, which gives it about 3mpg. (which is not far off any car driven foot to the floor in low gears). I Don't doubt it would be more efficient at prius-esque RPM's except there'd be so little torque, you'd struggle to get any acceleration.
Anyway, an F1 car does about 6mpg, which is pretty good, considering the speed of the things!

........at last!!!!!!
Someone has actually answered the question.
Subaru are in the business of making road cars. You know, the things you use to get the shopping, take you on holiday, drop the kids to school, get you to work....as opposed to something you drive around in circles and talk about at meets/pubs .
I expect my car to start first time, every time, last in excess of 100k miles without significant faults, be quiet and comfortable, have enough space for family and luggage.
I bought an Impreza because it does this and provides a bit of fun without compromising the above.
This is a very difficult thing to achieve and Subaru do a good job of it.
Now, if you take away noise and emissions restrictions and are prepared to compromise comfort and reliability you can make a pretty quick car......but a pretty useless road car.
Incidentally, does anyone think that there will be road tax penalties in the future for modified cars?

Wrong, the super dooper map is free .... the other parts are very cheap for Subaru.
The boss of Ford once said, in the 70's, that it costs the same to make a Fiesta Popular as it did to make a Granada Scorpio GhiaX (for all intents and purposes).
It would cost Subaru the same to produce a 550 BHP monster as it costs to make a Justy!!
That's just how it is ..... just because muggins on here pay £££££thousands for mods doesn't mean that's what it has to cost!!
This is probably the single reason Subaru do not do it - and a reason that everyone should stop and think very carefully about turning their Subaru into a TVR in reliability terms.
The current WRX is to appeal to the masses .... not the STi - nor would the 550 BHP version either!! It would be a niche product, probably about £34,950?
And as for not being able to drive it ..... well, yes, ban its sale to anyone under 45 as these kiddies have difficulty driving in any case
