Another quote from the same thread, especially for csd_19, who believes it's random to fit an uprated SMIC over an FMIC for stealth:
Aww gee thanks
The truth is that loads of people fit them for stealth reasons.
More like they've not told their insurance company

The road hazard thing is more American, as apparently their roads are sh1te.
And the American police tend to pull people over for crap like having a fmic or a pillar mount - can't say I've heard a whole lot of that going on over here? They also have the worry of the visual inspection part of their equivalent of our MOT, if it doesn't look stock (in certain states) then its no pass.
You'll get pulled in the UK for:
A) Driving like a muppet
B) having no insurance/MOT and pinging the ANPR cameras
C) sh1ts and giggles on the nights the police are a bit quiet and want to check you
D) your car looks like an absolute shed
On that thread you linked to there are 54 posts, of which 3 are from UK users. One of which (interestingly enough) compares his FMIC to the uprated SMIC he used to run
You can be stealthy with a fmic, just give it a light coating of black paint, job done...
I'm not saying that if you are tuning you instantly must buy the biggest FMIC you can for your ko3 setup - its all a bit of horses for courses and individual choice.
If you're happy sticking with a SMIC because a Stage 1 tune is as far as you're ever planning on taking the car then fine, if you're going bigger then a FMIC would suit your needs better.
