Does anyone reccomend a certain company, or have heard one company's are better over anothers? I know most of it is preference, application, price, and/or advertising though. I'm trying to find one for my truck. I do go off road frequently, either beach or trail riding, mostly during hunting season. And want something thats going to have the best performance, but not spend over $500 or so. I have only talked to one other person with a silverado, and he had the AEM brute force, and said it was the best one you can buy.
