The only thing i chaned since installing it is running temp towers and Max flow rate tests and i set these now i only mainly print in PETG so only ran test for PETG.
Added 10 deg to PETG Settings. - Bambu Had Set 255 i moved it to 265
0.4HF recomended flow 24 i got and set 26
0.6HF recomended flow 31 i got and set 35
0.8HF recomneded flow 38 I got and set 39
So the flows on the Revo Page for High flow were spot on and for me a but conservative bit, that might be becouse of the added temp.
