If I could get around 600rwhp for more than 1/2 the cost of a tvs I would be all over this. Right now there is no way in hell my wife is gonna let me spend 5k for a blower, especially after getting ccw wheels. As for warranty, don't care about that part, I am a tech at ford dealership so no worries there.
I got over 600 rwhp for way less than the tvs. MY combo is 2.6 upper, steggy port, and 10% lower.
