OK guys, i don't know if this has been done before, or even if i'm in the right category on here....
but the fact of the matter is I've read all about the advantages of the boost control solenoid replacement when running higher boost, but how does it work? what are the advantages? can i tune my boost through the 3port solenoid? can i stage my boost by gear? what does it really do compared to a manual/electronic boost controller? i'm lost here. the product sounds great in theory but if i go ahead and get it i dont want to turb around and have to purchase a boost controller on top of this. plus get it tuned.

any information, advice, experience is welcomed appreciated greatly
