While tracking westbound on V100 between ELX and MUSKY; Chicago Center inquired as to our position north of course. We responded that we were showing on course; and stated we are tracking the 277 radial outbound from ELX. Center replied that we should be on the 271 radial. I input the 271 radial and intercepted the course. Upon further investigation; our Navblue Charts+ show 277 course westbound on V100; while FAA issued charts show 271. In addition; Navblue Charts+ show a change from 277 to 274 after passing YOLUR intersection. With no navaid located at YOLUR; how can the course change? We were navigating in green needles because the aircraft had 3 MELs at the time.I suggest a review of the Navblue Charts+ enroute charts to determine if accurate data is being presented to pilots using the charts.
Captain reported navigational course error due to published Navblue charts depicting an erroneous course westbound from ELX on V-100 airway.
