Although yours may or turned out to be junk, many of us have bought the same kits, myself included. No matter what HT kit you buy, how it is installed will be major a factor. I've bought 4 kits and other then minor problems on the first build (coil), I've had NO problems on the remaining 3. I have bought from only two distributors, one I will not buy so much as a screw from again. Saying that, I don't have extensive experience from one distributor to the other, although reading here on the forum some kits seem to excel over others. All HT kits NEED some modifications done to them right out of the box...my $0.02
