That's what I thought the reason was for the 04+ not liking the manual boost controller but I wasn't too sure.
has anyone used a mbc with an ewg before? Would it actually work as well or not? I'm really curious to read this over and get a fully understanding of how ken's mbc/ebc works b/c right now I'm still a little confused.
So does the vacuum source hit the mbc first or the gm solenoid first?
