It's an excellent Service INFORMATION Directive. It is not REGULATORY, so you can set the engine up as per the SID, then add FF until the Target EGT is correct. We have found that the best operational set-up is to set the unmetered LOW pressure at the bottom of the range and the HIGH pressure at the top of the range, then tweak the max FF up. This results in good mixture at low powers and adequate FF to keep CHTs and ICPs under control at high power settings.
