I didn't know which way to go - so I picked the middle ground :P
first 1000kms regularly hit 5000rpm and a couple of times went a bit higher (by accident). Since the 1000kms are up it I hit vtec in most gears while driving (long straight open roads around here)

Further to h22a_accords "drive it like you stole it" comment - a friend of mine did the same thing to a factory BA xr8 except starting from the driveway of the dealership
No dyno figures, but the dealership were amazed at the performance, made mention of the fact that none of the fpvs coming through were even close to it.
He's currently got a my06 wrx which got the same treatment - redlined in top gear on the trip home from the dealership
