I am trying to elimnate boost spikes in the higher gears and I was told a good route to go is the grab a MBC and run it in parallel with the N75 valve and set the boost a bit lower. I am runing GIAC X plus full exhaust.

Does anyone have instructions for installing the Forge underhood MBC that is sold by ECS tuning. Any help would be appreciated!

No one has any help here for me?
