I have had the same issue using Loadrunner while adding the Oauthheaers, The problem is the headers are generated on the fly and cannot be captured by web_reg_save_param, and hence cannot be passed with web_add_header functions. However, Jmeter has a way to do it. There is a OauthRequest Sampler, which can generate these values.
