Like I said, it's a setup issue.
power is only a very small part of the car as an over all package.
As a road car, mine felt quite lairy with 230bhp from a ko3S. As I developed the chassis to handle more power, that 230bhp started to feel really rather slow as the chassis was more well equipped to deal with the power.
At 380bhp now I can use all the power in 2nd pretty much. You have to remember that driving is still a skill, you can't just mash your foot to the floorboards and expect it to do everything for you, you need to drive to suit the conditions of the road / track.
Handling wise, one of THE best things you can do on a mk4 is to fit LCR wishbones and hubs. These behave far better than the stock items with a much better camber curve through the range of movement, as well as giving more static camber and caster. Fitting a quicker steering rack from an LCR also does wonders for steering feel, and in turn, driver involvement.
