I am looking at ordering a Phoenix chip for my stock early '99 7.3L. I use the truck to commute, tow a 2500lb boat, and a small 5500lb fifth wheel. In the future I may have a slightly larger trailer to replace the 5th wheel however.
I am looking at getting the following tunes:
Stock
40t
65t
80T?
80E? 65E? Both???
100P?
My questions are should I get the 65E or 80E? Is there much difference on my year of truck? Would I be better off getting the 65E and 80P and not the 100p?
Any input would be greatly appreciated.
