most F40's are at 550 to 600 bhp?

Having watched Jethrow Bovingdons review of the 488 he mentions briefly that a lot of F40's are now tuned to around 600bhp? I am curious as to what the performance is now like in this state of tune, that hike in power whilst weight remains approx 1100kgs! it must match or better, say a GT2 RS amongst other more recent cars for example?
