I am going to be running a grimspeed 3 port ebcs and want to know if I should leave the top 2 ports open and use one of the bottom ports and plug the other lower 2 ports? I am also wondering what psi spring setup should I run if I plan on running 30 psi on a 6466?

 

You will typically run boost to the bottom port and the controller to the top port. Rule of thumb is that you can run boost up to double the spring pressure. I would recommend an 18psi setting although I personally run 24psi springs on my twin MVS's for daily 30-33psi.

 

Thanks for the input I appreciate it

 

good info!
