    Hi all,
    Just got my f40 back from major.
    Runs great to 4K and then acts like it hits a hard limiter. Runs great below that. Any ideas?

    could be bad spark plug wires or spark plugs, could be fuel pressure issue (clogged fuel sock, weak pump, etc)...

    Additional info. The tach drops to zero (but the engine doesn’t) at the same time the boost drops.

    Did you install open LPM pipes? Could be it's spooling up too quickly and the waste-gate is opening at 4k.

    Warmed-up? A bit of overboost maybe, if no ...?

    Who did work on it? Sounds like they don’t know what they are doing….
