why spend 75 on a turbosmart manual controller when you can make one for under 10 bucks? ball and spring, just as accurate. seems like you're throwing your cash away too :P:

LOL, You must be assuming that I have never tried a home depot controller for myself.

I have and you can go test them both out for yourself and you will see what I mean. They don't work worth a damn. I get creep like no tomorrow when trying to use a home depot controller. I have had more than one guy come to my house from here on the forum telling me that they had a boost leak and it turned out to be a BS home made boost contoller. And I don't see the sense in making parts that will not even work properly when I can drop 60 coins and be done with it. I don't sit around here respouting off shit that I read somewhere man. I am basing my opinions off my experiences with all three types of boost controllers that have been brought into this topic. But hey WTF do I know right?
IMO home made manual controllers are junk.
