I am researching all three of these Superchargers for my car. I was wondering if anyone here has experience with any of these and why you picked one versus another. I'm just starting my research and with the dollars involved here I want to make sure I select the right one for me. Thanks in advance for everyone's help and input. Has anyone installed one of these themselves? I've read some of the install directions for the ProCharger and it looks like a job I can handle with a little help.
