    787 RFI RAVE Valve Opening RPM

    At what RPM's do the RAVE valves open? Reason I ask is my 787 RFI sort of surges below 5500RPM, once above that RPM it smooths out and noticebly feels gruntier, RAVE's are clean and not sticking.

    I battled that one myself for a year and a half until i reset the TPS setting. once the Computer knows exactly where the butterfly is at, the engine will run very smoothly. Its as simple as the fuel/air mixture being all messed up for a given engine RPM, most noticeable just above idle just as you are about to get up on the plane
