Blimey, that's a lot of bhp already mate! I'd be interested to hear what you've done... The Polo GTi boys would sell their soul for this kind of power! As for this product, it's BRAND new (only announced this weekend), so no one has had it done yet. Of course, I'll let you know as soon as someone does!
