As previous threads have said above 360bhp your looking at a FMIC. Most specialists charge approx £200-350 to fit so its not a quick 10min job, depends also on model of Scoob you've got (bumper off and poss some cutting).

For less than £50 you can obtain and fit a charge temperature guage which will show air temperature at your throttle body.
On an STi 3 with relatively few mods, making 335 bhp it is possible to reach 70 deg.C charge temperature with very little effort. Once the car is fully warmed with a charge temperature of say 25 deg.C. it only takes a couple of sprints to 100 mph to have 70 deg.C charge temperature.
Similar figures for an efficient well designed FMIC would be, cruise at no more than 2 C. over ambient and after a couple of 100 mph sprints it is unlikely that the charge temperature will have risen by 10 C.
Initially I was totally against an FMIC and you do not need big power to get additional safety from an FMIC, properly designed.
I suspect those that say an FMIC is not necessary are repeating what they have heard or read and have not taken the trouble to actually measure charge temperatures.
