Afternoon all and Merry Christmas, thankyou all for the comments and help in the past and i am sure in the future too. We have had the power curve done on ours this fall, it does make some difference in the power department but hate to whine and complain but still just uses that much more fuel all the time while in the field, not so sure about these Sisu engines in the combines as of yet, they may shine in the tractors but not this application. I was told to leave the CDF and not touch anything by the company and dealer but am open to suggestions, anyone got any ideas as to what i should be doing with the rotor and the cage, thanks again for all help.
