Pslewis is completely correct, you do not need a re-map if you are simply uprating the intercooler and moving it to the front of the car.
Furthermore at your level of mods, a FMIC will make bugger all difference anyway, you are best off spending your money elsewhere.
MY BNR32 has a massive trust FMIC and it is running at 475BHP and I have been advised by my tuner that even at that level of tune there was very little point in fitting an uprated item over the standard.

But you arent uprating the intercooler and moving it are you.You are increasing the volume of cooler air into the engine by 4 or 5 times if the core sizes were the same id be inclined to agree but they arent and as i say without introducing increased fuel to compensate for all the extra air coming in the MAF wont read properly causing the engine to run lean

This is the complete and utter ignorance that I am trying to talk around ......
The SAME air enters the engine, cooler air, so more dense .......... NOT FOUR TIMES AS MUCH

the core size if the fmic is approx 4 times the size of the standard unit.Therefore the volume of air entering it is much more.Even you can understand that surely,you cannot expect the same amount of air to enter something that is so much bigger.I think the only engineer you qualify for lewis is a brown pipe engineer.Back to simple maths for you boy

I assume you are not actually an Engineer?
The valves are open for the same time, the capacity of the engine remains constant, the manifolds (not headers!!) are unchanged ..... there can be no more air entering the engine - it is simply more dense the cooler it is!!
You are trying to tell everyone that you are Paul Daniels and can cram a gallon into a pint pot ...... it ain't happening!!

May I simply suggest that although, as Pete quite rightly points out, the tuners on here can hardly be referred to as an impartial source, they do have extensive experience, often to their own cost, of what works, what doesn't work, what is safe and what is unsafe with these cars. Most of them are from an engineering background themselves!!
Even the most highly qualified engineers on SN (and very few of them have actually stated their qualifications and experience with performance car tuning) can't lay claim to having anywhere near the experience with these vehicles that the eminent tuners on here have: literally thousands of cars pass through their hands in a year. How many of these cars do SNs engineers deal with?
You want to install a front mount, CAIK, or other mods without a remap, or a least checking with someone who has a wideband AFR and Det cans to make sure the car is running safely, the best of luck to you.
BUT
If things go **** up, don't come on here complaining about Subarus having chocolate pistons etc... or thinking that you're going to get much in the way of sympathy, cause you have been warned.
That's all I'm going to say on the matter, getting a bit tired of banging my head against a brick wall to be honest!

It doesn't matter how big the intercooler is, it is how efficient it is at transfering heat that matters... to be silly fit one ten times larger and you get 3000 bhp.... don't think so !
See PSL is right, and as for CAI I absolutely agree that needs looking at immediately to avoid a melt-down ! Even a piece of "Zero Sports bling" tubing for the intake comes with a warning to re-map....
As for re-maps, as the budget hits and Labour go back down the route to financial meltdown.... as last time ! Then demand will fall and prices should follow.
IMHO

P.S. I'm really bored to be at work till 9:30 pm.... Groan !

ok, bigger intercooler, yes you can get 4 times more air in there, but, thats volume, and that would be taken into account by the MAF, and ignoring that, no matter what you do you get 1 unit of air in for 1 unit of air out, so having 3 units of air in the intercooler is totally irrelevant, the engine can only use what it can hold, albeit under higher pressure than normal. I wouldnt be suprised if there is a temp sensor or pressure sensor after the intercooler, that the way the ecu can work out the density of the air coming in. PSLewis is right, but, it wouldnt do any harm to have it remapped anyway.

Had to kinda lighten things up a little bit
I can see where PSL is coming from, but I can also see the need for a re - map.
In regards to the question that was asked about a re - map being required, thats just gona be an on going debate on this thread. Whats probably relevant IMO is does Phill actually need a FMIC? Answer = No
Reason as stated by NS04 on Phils previous thread, myself and others is that the standard intercooler is good for 350BHP. FMIC should be considered when pushing beyond 350BHP.
Also, Phill has got a UK spec car, same as mine, and its not gona like being pushed to this kind of power, and if it manages to get there, its gona go bang very quickly along with the gear box.
So Phill if your reading this mate, save the money your gona spend on your intercooler and spend it some mods thats going to have an immediate to the performance of your car. Figure out how much you wanna spend, and speak to one of the tuners. Unless your going to uprate everything internally, or go for a bigger engine, a front mount is just not needed at this stage of tuning.
Good luck mate

As an aside, one of the big benefits of a TMIC is the very short intake air path (after the IC) - putting a FMIC on would mean quite a bit of extra trunking, which results in the air warming up on its extra travels (we all know how hot the air is coming out of a tyre inflator).
Therefore, the gains in the cooler position will be somewhat diminished in the warming effect of the extra trunking.
