I have a "new to me SR22" that has Entegra PFD/MFD along with IFD 550/440/DFC90 installed.  Everything works great other than the Synthetic Vision attitude display on the 550 is always showing a pitch down display and never changes.  It is this way on the ground or in the air.  The heading is properly displayed, but attitude is wrong.  I did not see any information on calibrating the unit or any troubleshooting in the manual.  Sorry for the sideways picture - new to this site.  Any info is appreciated.

Section 7.5.22 of the Installation Manual has the calibration instructions that might help with your situation.

Thank you for the manual. The calibration process fixed the issue.  My installation required a -28 degree offset. The TAS was also not set which I assume helps aid in accuracy in cruise flight.

Same issue here. Just installed an IFD550, but the shop didn't configure this.
