Are you saying that you installed HIR1 or 9011 bulb into your high beams? HIR1(2530) is supposed to be only 430 lumens more than the stock H9(2100) bulb. Do you really see that much difference from extra 430 lumens?
And by "factory xenon" do you mean you have factory HID in your low beams? How does the factory HID compare to your new high beam HIRs?
