That's a good post you put up for the group. I installed my 6lb pulley this weekend (and NGK TR6 Plugs) and I am still smiling. Predator pulley tune program and boosting up to 14lbs now. I had to look at the gauge a coupel times to be sure. I had NO PROBLEMS AT ALL (except last plug on passenger side) it was kind of tricky but I won.
