Just trying to figure out what is the best all around programmer for my truck. 2003 5.4L F-150 Supercrew FX4.

 

Well, in my experience, I have had good luck with the Hypertech Power Programmer III. Granted I haven't used one on my KR (yet!), but I used them on my Z-28's and they were awesome.

I'm sure there are other brands, but it's just my 2 cents.

Good luck.
