So I have been using my AC for a week now and my power level has gone down. It will works fine with no power loss with the AC is off,but when I turn it on is like I'm pulling a trailer. The only codes the ECU shows is 55 so it's good,the other thing I could think of is a air leak somewhere,but where??

you will notice slight power loss with the ac on. its should not be much though, when i use my a/c on hot humid days the cars feels fine. are you experiencing a major loss in power?
