I'd prefer the one for my injectors. If I had a 2000 f-car, which came with 26lb injectors, I'd copy the table. If I upgraded my injectors to the 28lb injectors that came on the '02s, then I wouldn't copy the IFR table. It's not a blind copy. The tables were set the way they were set for a reason. I just gave you my opinion. In the end, it's your car. So, do what you want.
