What to do???
I have a friend that has a 2003 F-350 4 door, dually, 4wd, FX4, Lariat, Automatic. She just turned over 101,000 miles, so she has no warranty left. She pulls a 3 horse slant with living quarters quit often. She wants a little more power but is mainly concerned about her transmission not holding up. Do yall have a chip that will add some power and firm up shifts? I want performance that is very reliable.
Thanks.
Thanks.

Yes, but head safe for one is not always the same for another. People blow head gaskets even without tuning.
