The advancer will rob you of a few BHP, if your peak BHP figure is important to you I'd fit it after you have had some runs with the OEM part. As it literally takes minutes to fit maybe you could take the advancer with you to the testing station and get another set of runs done after fitting, I'm sure I'm not the only one that would be interested in comparing the results.
