They took painstaking effort in making sure the conditions were the same for each dyno run. At least they made the effort to dyno. Saying E3 plugs are better is no more stupid than putting a 3" exhaust on a stock 5.2 and saying it has more power from your seat of the pants feeling.

guess you zj boys don't know much about a more efficient and productive engine or how to light foot it for a whole trip. i touched the brakes once, and that was when i pulled into the parking lot at my destination. 55mph the whole way was a buzz kill but i kept it groovy baby ;0) a little hendrix through the infinities to boot. it was like 1974 all over again.
You sir, are an idiot.
