It does have a lot of good information but it also has some bogas crap too. For a few years they were promoting taking your FSD off your pump and butting it on a heatsink, not that thats a bad idea but to leave it in the hot engine compartment? and if that wasent bad enough the heatsinks the were selling were over $160. for an aluminum heatsink! And when it comes to "group buys" forget it! they don't allow it. But I do have to say that they do have about 50% great information.
