Might have something to do with the 4.10 gears and low powered engine. Also, I don't recall being asked what the rig would be used for so maybe he assumed hill killing or something. The more I think about it, the more I can visualize the shortcomings. You're either riding the converter or by the time it flashes, it wants to break loose. Most likely operator error on my partI agree. That's why I was kinda surprised after hearing what PTC spec'd for BeerJ's.
