Hook up a MBC. This will correct your problem. The factory spring is set to 11 psi.

What i dont understand is: if a MBC will solve my problem, do i still have to replace my possible non-stock vacuum hoses? Or does the MBC come with different ones?

The first service manager (not at the dealer i bought from) was cool as hell. He knew i had just bought the car, saw that it was basically "slapped back to stock", and he said i was cool, im covered under warranty, don't worry. Now that you mention, im not even sure about my "2nd owners" warranty. Didnt know it existed. Im very tempted to get a MBC to solve the problem, but would rather go with the hoses to keep it stock. Does the MBC work with my existing hoses or does it come with some? Im really confused on that part.

I don't know about all MBCs, but the Hallman comes with one vaccuum line that I cut in half and used to connec my MBC to the wastegate and turbo nipples. They are just long enough for me to mount the MBC on my radiator fan.

Hopefully once i get the pics posted you guys can tell me if they are stock or not. If they are, it seems that will be a big problem. If they are not, seems easy to resolve. Knock on wood!

I'm having the exact same problem as the thread starter. I just bought a used evo, and the previous owner had a mbc on it, but she took it off and the car is maxing out at 11psi, and I also have a defi d gauge. So if I have aftermarket lines, without the mbc installed, that is the most boost I will get. If I were to hook up the stock lines, would I once again hit the stock boost setting? I could just hook up the mbc, but I just wanted to know if I return to factory lines if everything would go back to normal. Thanks

I had this problem, turned out to be the turbo was shot. The dealer said they would pay for a new turbo but not for the install, which was 450$. I decided to just pick up a low mile turbo for 300$ and put it in myself.

This hose should have a small restrictor inside them that limits the amount of air through them. If this restrictor is removed you will not get more than 11-12psi.

Hey Doug at Top Speed..i am the tread poster...i could be at topspeed in 2-3hrs. Do you think you guys could solve the problem?? I just talked to your sales and he said you have 1 Forge MBC in stock. I cant take this 11 psi anymore! What do you think?
