It will help control how the boost comes on and is very much a must have in the mappers eyes as it helps map the car to as best he can.

classic ones work fine just need a small wiring mod that the mapper will do when fitting, I bought a prodrive one for mine as it came with a small interconnecting loom so was just plug and play, but don't think they are easy to find.
