Iam just wont to know do i need it or not if so why do i need it and if i do need it for my turbo set up Iam only going to run 6psi . some people say i do and some people say other thanks

 

well you should have asked in the forced induction/engine management section. but yeah you need some type of engine managment when it comes to a turbo, a fmu would help. but not the best as far as fuel goes. try lookin into either uberdata or turboedit, im not sure what type of car you have so youll need to research some more on it. just look in here https://www.homemadeturbo.com/forum/...threadid=14497 it will tell you what you need to know
