Saw a dyno somewhere few days ago only.
I bet its more than just a map to get well over 500fwhp
Full bolt ons (upgraded intercooler, intake, down pipes, exhaust and a tune like JB4 or a remap) are good for well over 400

You'd need to upgrade the turbos for over 500 - 600 territory, there's one I posted a little while back with 613 bhp with rob beck turbos.

So unnecessary though I'd wonder when the gearbox would say fcuk you and pack up too! But what an engine...!
