I had an alternator rewire on my old car with good results for what I paid. ($0 My friend does auto installs and deals with wiring. He made em for fun.) He actually just made me another one for the Regal. That along with the S1 volt booster I should not have a problem powering my HIDs anymore. Not that I really do now, but once and awhile I do come out to only one on. Plus my lights still dim some when at idle.
