Focus St 225 intercooler

[8cylinder]

I am looking at getting an uprated intercooler for my 225 St.
The one I am looking at is the radtec cooler from pumabuild,has anyone had experience with radtec?
What sort of difference am I likely to feel in driving the car.
The car also has 3 inch down pipe,3 inch decat,centre silencer delete and group a induction.
What sort of bhp will I likely to see on the rollers before it is mapped with the above mods?
Radtec are making a pretty big claim of 34bhp with there cooler,I doubt that but some sort of gain would be nice.

Why does it need the lower bumper and plate moved?
Looks like it might need the horns moved as well.
Does it drive any different since u put the cooler on?

Be better mapping the car first then?
