I want to replace the ceiling in my living room with a tray ceiling. The problem is that there are 2x4 enginered trusses supporting the roof. The current trusses will not allow me tray the ceiling the way I want to. Can I sister 2x6's up to the 2x4's and partially remove the trusses or do I need to completly replace the trusses. Any information would be very helpful.

Trusses are designed and engineered with the various components to work together in providing an free span unit.
Cutting them without proper re-engineering wouldn't be something you should entertain or attempt.
Doing a trayed ceiling is tricky to do in a remodel situation since it involves significant structural work in raising the ceiling height.
Depending on the existing ceiling height you might be able to frame the area around the perimeter to lower this part of the ceiling. This will allow the center section being higher to give the look of a trayed ceiling.
