If I understand you correctly you need to change the clip tempo to fit project. however you may need to edit the clip map first depending on how far off the clip is. This is an internal clip mapping and nothing to do with the actual project tempo. Having said that you'll save yourself a lot of time if you change Sonar's guess at the clip tempo close to the actual project tempo.
CLip mapping is explained in one of my youtube videos
here. Once that's done change the clip tempo to match the project.
