Default JB4 W/ MHD BEF Boost Problem - 07-12-2019, 04:38 PM

Hey guys. I live in Houston Texas where it is hot as balls. I just got my E92 335i back from a shop that did a turbo swap from stock to MMP 1K turbos. They also did relocated inlets and a silicone outlet. With that being said I myself did a MHD BEF Stage 2+ on the car and I am running it on Map 5. Some pulls go up to the full target 18 psi of boost but sometimes it gets limited to 10 psi then sometimes 8psi.. the pulls are done always the same.. a 3-4 pull. Could this be the JB4/MHD? Would it be a boost leak? Anyone experience this before?
