i've got a chargecooler on mine. works well to be honest.i've just bought a act gauge so i'll let you know how well soon i guess the only downside ( could be an upside for some ) is that it's not as obvious as a large intercooler i.e can't see it very well,and i guess they are quite expensive.

pics below, you'll see it's not very 'in yer face' like a mahooosive i/c
