Wondering if anyone would care to share their experiences with operation of their TSIO550E in a IVP.
We normally operate around 18 to 20,000ft at 28inches and 2500RPM. Running ROP we are usually set up around 1600 TIT, max EGT  is around 1550 to 1560 and fuel flow is around 21.5GPH (CHT’s are around 360). We use a Vision Microsystems engine monitoring system. Usually, indicated airspeed is around 210 and TAS around 250. My guess is that we are around 60 ROP on the first to peak cylinder.
When we go to LOP it is fairly straight forward to get the TIT back to 1600 but the range of EGT’s is worrying...from as low as 1430 to as high as 1570...if we lean further to try and get the highest EGT back to around 1550 we start to run rough, so abandon and go back to ROP.
Is this a job for balanced injectors or is there something we are missing?
