I've got the Bullydog timing/pressure box which is no longer available. I liked it fine but got nervous about the pressure increase so disconnected it.
It drove fine, very nice power increase, dynoed over 400hp on the high setting and gave a small MPG increase. I didn't like the power curve, way too peaky, not enough ooomph at the bottom end.
If anyone is interested in it I'll make you a deal on it. PM me.
