And just to correct you, a FMIC does not gain or lose on power, it gains or loses on response, which in short means that it will either cause more or less lag, more or less air density.....

in fact, if you have a FMIC same size as the std one and your plumbing has the same flow rate and total capacity, it will give you better performance (Meaning response) than the original one in the original position due to better cooling, thus allowing you to access more of the possible power that is already available, more efficiently...... Kind of like the difference between driving on a cold day vs a hot day.....

When you have a larger FMIC there is more cooling adding a higher air density, allowing you to access more power, but at the same time what your actually feeling is not loss in power, but loss in response, delayed boost due to compression time.

So no, no loss or gain power wise, but yes there can be loss or gain in response time. Less or more lag.

I'm also basing the above factor on merely just installing a fmic.

Also remember boost is slightly increased when you install a fairly larger ic so power is affected.

And I am thinking of doing the install myself as a little project.
