Bryan - I've had a Vortech for about six months now and have had no problems to date. I have learned that probably the single biggest item to be concerned with is the ability to have your car custom dyno tuned once the SC is installed. Both Paxton and Vortech make excellent products which will be very reliable and very powerful, however if you do not have easy access to a shop with a dyno and the expertise to tune your SC'ed car you're not going to get near the potential or your desired safe 400 rwhp. I am currently going through the giant pain in the rear of scheduling someone to actually come to my town to custom tune my car (unless someone can recommend a local mastermind tuner for Jacksonville, FL.....please, please, someone give me a strong recommendation). A local shop has tapped me into someone who is suppose to be a "genius" at tuning a 4.6 with a supercharger, but he is not local, so I'll get custom programs for my computer, but this is NOT to be considered a custom tune by any means (I have gotten significant power gains via this remote tuning, but I am also risking my engine because the first round of this I had significant detonation). You must have someone actually lay hands on your car with a dyno to get it right. Anyways, good luck!
