 2019 BMW 440i MHD Stage 2+ E40 MapModifications: Catless Downpipe | Supra/Tu High pressure fuel pump | Dual resonator delete | Quaife Limited Slip Differential |
I had some issues where boost was falling short by about 4psi on average. Vehicle checked by mechanic for boost leaks and none found on smoke test. Re-flashed MHD and issue resolved.
