Fuel Management systems with high boost?

[xXeclipstasyXx]

It's obvious that you need to upgrade your injectors to 500-550cc when running high amounts of boost, but do you need to invest in a fuel management system to go with the new injectors, or with the stock system adjust the the higher flow for you? As fuel management systems are rather pricy, i was curious as to whether or not they make a world of difference, or if theyre a necessity....

They are necessary and if you are going to run high boost (20+), go with injectors bigger than that. 500's aren't even worth it unless they are free.
