As mentioned, it's not needed but it will be of a benefit to even a standard car.
I strongly disagree - especially on (a) an Eddie, (b) a remap, and (c) an Eddie with a remap.
Basically, in that scenario, you've paid not one but TWO price premiums. You are effectively throwing that money down the drain if you do not upgrade your intercooler.
The OEM plastic intercooler can be, at best, be described as merely 'functional'. Efficient it is not. Nor is its placement ideal. The S3 cooler is much better, but is still compromised by its mounting position, hence why Forge developed the Twintercooler.
I have to disagree with you Shaun to an extent.
If your remap has been wrote for your car with it's fitted parts, whether it's OEM or aftermarket, you can have your car setup running stage 2 power with decent results ..mine runs 330bhp stage 2 and 325lb ft, boost max at 1.275 bar boost, so turbo is only being tickled running her stock Intercooler
tuned by Niki gower at R -Tech .
We are now coming into warmer temps so if we actually get a summer this year then it's worth having one.
If you do chose to add an intercooler , then it's worth having your remapped tweeked with the further cooling enhancement.
If you choose some generically tuned map like Revo then you'll have more limited map adjustments to get the best out of the engine.
Personally I will only be changing mine if my old OEM spouts a leak as it's plenty fast enough and has been logged to safe parameters.
So it's not a " Need ".. More a "Want" lol. Part of the slope of modifications
If your aim is more power then do it Woody.. But remember a fwd car can only handle a certain amount of power without getting into wasted power/grip problems, but that's a whole different subject and I'm digressing
