Message: [QUOTE="DZL JIM, post: 1458685, member: 153"] You will not limit boost in the entire system by that little pop-off valve. It would take a larger sized dump gate to do that. Your pop-off should dump pressure off that little line going to the MAP and that's about it, doing what it's intended to do. But I have to ask why? I ran over 60 psi on my truck with no boost limiter and it never de-fueled. OBS trucks don't need the fooler like the SD maps do. Edit: I re-read the posts here. Many guys responding have SD trucks, and the 6.0 maps are the same as the 7.3 SD map sensors, hence the need with those trucks, too. [/QUOTE]
