We had this discussion on the SEN thread two years ago. In broad terms the specification of the Volotea aircraft, as evidenced from the register details, indicates the engine thrust levels are those appropriate to the HGW version, but the MTOWs are those of the Basic Airplane. So they are either HGW aircraft with the certificated MTOW deliberately restricted to reduce airport and en route charges, or Basic Airplanes with engines uprated by the simple (?) plugin and software change. One certain conclusion is that with these lower MTOWs their maximum full payload range will fall well short of the figures achievable with an unrestricted HGW.
Once again this highlights the difficulty of using internet sources for determining aircraft performance capability. Manufacturers data on the internet is not wrong but usually only covers a very limited selection of the weight variants and engine thrust options available. So the chances of the published data accurately reflecting the capabilities of a particular operators aircraft are not good, a situation that is most apparent when considering operations from restrictive runways such as SEN and SOU. Wikipedia data is even more generalised and hence of little use. It means that one has to be wary of being too prescriptive unless the source is from the operators own data.
