An interesting rabbit hole for me this afternoon...
corksport.com
"The stock intercooler core is 24.5” wide, 5.5” tall, and 2.625” thick. Our plan is to fit a 27” wide, 6” tall, and 3.5” core without any trimming. This sizing combined with a low-pressure drop will be good for 400WHP with no issues! Because the Mazda 6 comes with just around 200WHP from the factory, this sized core provides plenty of room for upgrading down the road without causing excessive boost lag that can occur if an intercooler is simply too big. "
-Corksport doesn't say it adds any HP, but can provide the ability to add upto 400 WHP"
Then on the product page:
Get more from your Mazda 6 Turbo 2.5L with a Performance Intercooler Upgrade, better flowing core, larger size and free horsepower with nothing but a bolt on.

notice in the graphic provided of the product Corksport claims
3 to 9 WHP (wheel horse power)
3 to 12 WTQ (wheel torque)
but will all the fancy temperature and pressure drop graphs there doesn't seem to be an actual dyno graph to be found.. very odd.
out on the interwebs about intercoolers in general there are some nuanced answers:
A turbocharger is a great way to add power to your driving experience, whether you are racing on the track
www.vividracing.com
"Will a Bigger Intercooler Increase Power? – Without proper tuning, an intercooler by itself won’t increase power by any substantial amount, because your OEM ECU tune may not increase boost or ignite timing when it sees safer charge air temperatures."
but then you read:

www.ausbodyworks.com.au
"Most intercooler manufacturers aim for at least 70% efficiency in being able to cool compressed air for the turbocharger/supercharger. Additional aspects also come into play. These include: the air pressure drop that is caused by the design of the intercooler and its piping; the size and type of the intercooler; or the position of the intercooler in your car’s engine bay.
Depending on all these variables, an aftermarket intercooler may be worth power gains of between 5% - 10% above the gains that an OEM intercooler may provide."
some fun math in this one:

general 5% to 10%
Improve the power of your turbo engine with an aftermarket intercooler. Uprating the intercooler can achieve the benefit of power gains of 5 to 10%, we look at the benefits of fitting a larger intercooler to your car.

So... what you are asking the collective crowd is really:
"Has anyone ONLY done the Corksport FMIC and seen HP gains real world?"
"Has anyone taken their vehicle to the dyno prior to Corksport FMIC and then after the install?" "What were the real world results?"
