You'll see massive gains midrange as the VTEC crossover is set to where the high cam starts to make more power then the low cam which is typically around 4,400rpm to 4,600rpm, rather than the artificially high point where it was set by Honda.
The car will therefore have much more punch when in normal day to day driving. It's strange at first, but you soon get used to it.
Figures depend on which dyno the car is mapped on, for example Artech/Eurospec's dyno is notoriously harsh. However if the car runs around 197 stock, then you'd probably see anything from 215 to 220 with those mods, though I've seen higher recently with just an intake and B-pipe. Like I said though, the main gains will be in the mid range, anything up to around 35-40bhp, and lets face it, you don't drive everywhere at 8,000+ rpm.
