Chip,Programmer, WHICH?
1998 Ford Expedition 5.4 4wd, Stock except for exhaust. I reguarly pull a 20' race car trailer behind this thing and was wondering if the programmers, Superchips and Hypertech, or a Diablo chip would give me better performance. I like the fact that the programmer will let me tailor the thing if I change anything on the truck, but I am looking for the best performance ou of it when I am pulling. Please help. Thanks in advance.
