A. Silver bullet, no 225 was not used in an arbitrary fashion at all, it was obviously used as a example.
It's completely arbitrary. When I see 250+ towing, that's too hot for me. It doesn't matter if you feel the truck is fine at 225 when I'm concerned about it being at 250. You're focusing on 225 and suggesting AGS is not needed, I'm focusing on 250 and saying "that's too hot for me".
B. I was trying to say that any vehicle is probably better off without individual changes being made to the engine by mostly individuals who are less informed than the factory individuals.
And I'm trying to say that it doesn't matter what the "factory individuals" have done to my truck. I'm not comfortable with 250. I own the truck, I get to make that decision.
And again, remember how the factory individuals have shipped some trucks without AGS. Clearly they don't think its a required feature.
The factory individuals also say that you don't need to swap out the transmission fluid, but ZF who actually designed and built it says to change it out every 70k miles or so. Guess who I'm listening to.
C. "Grocery getter" is a derogatory term used by people who believe that their way of defining a truck is the only way. My pickup is never off road doesn't haul a trailer doesn't haul a heavy load, but the pickup bed is very utilitarian to me it is used quite often, to haul bicycles, garden supplies, groceries, stuff I use to fence my yard, animal feed, etc,etc. And now it has more stuff in it than I could ever get in a SUV. It does "get groceries", but it's used for far more than that. One of the reasons the first pickups were built was to haul high volumes of stuff around often groceries and the like to the small stores. Pickups were not originally heavy haulers, used for off-road or to throw a trailer. Although those are certainly valid uses for pickups today.
Stop focusing on "grocery getter" if its bothering you. The point of that was not to make fun of anyones ride, the point of it was to say how this AGS delete can benefit those who work their truck (me), and might not see any benefits for those who don't (you).
BTW: I consider my truck a "grocery getter" when it's not towing as well. It's my daily driver, I drive to work, I even use it to get groceries. The times I'm not towing with it, I could make do with a honda civic.
As I said, the term was not meant to be offensive, that's your choice.
Many of us call it that because in reality, it's a very accurate phrase, and everyone knows what we mean by it without having to spell out in nauseating detail what the truck is used for.
