    The theory is good but, you'll need other mods to make the most of it. big valve head,high lift cam, free flow exhaust etc.
    the usual tuning bits and pieces.

    Got rid of the cat too ?

    Cold air is denser so gives more power but, as with superchargers there is a limit to the amount of air/fuel the engine can process.

    The standard intercooler should do the job, A thorough clean may be an idea first so, its as efficient as possible. See if that makes a difference...

    Try a K&N air filtre too.

    Be interesting to see the results.

    After market intercoolers are good, but you will not see any significant increase with the mods you already have.

    You could look at this another way, your 120 runs the same intercooler as the 150. This intercooler is perfectly OK with 150 cars running a re-map so it will be perfectly efficient in your car.

    If I remember correctly the Vectra VXR runs the same intercooler.

    as maverick has said the vxr is the same intercooler so is able to handle anything you put on your car

    i think you need to find out what your car pushes out first on a rolling road to see if the map is running right on the car
