Beans makes one as well, very similar to Stricly Diesel's. As for who has the best, I'm not sure.

 

so 25 - 30 psi is about the max before the turbo goes? my buddy hits about 35 on his 99 when he lays in it. and it's a stock turbo but he has a chip, intake, exhaust, and injectors

 

No. It really depends. A turbo wont last long boosting like that all the time. I can push mid 30's if I'm really getting after it. If i did that everytime i came to a stop my turbo would give up within a few weeks I'm guessing.

 

where do you install the valve? pics?
