New injectors you say? As in "new" new or just new to the bike? Tip sensor is unlikely to make the thing bog down. You'd expect it to cut out entirely. I'd go for removing the TRE first then see what happens. You are best off starting from a "stock" baseline whilst trying to debug the thing. Next port of call if the thing struggles under load would be the fuel pump/filter. You can do the flow test to get an idea of the condition of the fuel delivery.
