I am not sure if this is the correct forum for this question but I need somebody that is familiar with Supercharged E55’s to look at my car close to home. My 05 E55 just isn’t running right and I really do not have time to work on it. My supercharger does not seem to be engaging anymore and I have an exhaust leak (Really embarrassing to drive right now). Does anybody know of a good independent in the Santa Clarita, CA area that knows these cars and performance parts? I really do not want to spend tons of money on diag time just to hear what I already know. PM is ok. Thank you
