I have seen some recent statements about people worried about installing a S/C themselves, and worried about the Roe Kit. I guess I fail to see why so much importance is put on sending this to a tuner. Sure for getting everything fine tuned for optimum performance OK I understand this, but to get it close what is the concern? If you take your time, have a set of service manuals, and are familiar with the basic mechanics of working on a car what is the mystery of installing the Kit especially if it comes with a great set of instructions and all the install pieces you need. There are also other great tuning tools out there like the Innovate Motorsports LM-1 A/F meter to let you test the car yourself.
