How should your car accessories be set while you want to have the most power avaliable??? should you have your air off? stereo off? how much does your a/c take away?
turn everything off you can the reason you loose power when tou have the ac on is because you are turning the ac compressor which compresses the ac and it also has clucthes in it that turn it off at WOT and the radio just draws current which means less currnet to the engine the ac does draw about 5-7 hp i believe
