whats the best box/chip for my 2000 f250 powerstroke I want more power and fuel mileage which company is the best edge, superchips, bullydog, etc

 

I believe for the 7.3 most would say a dp tuner with custom tunes. I'm sure the one of the 7.3 boys would be here to confirm that or something else that is preferred in a bit.

 

when you say dp tuner do you mean diablo tuner?

 

www.dp-tuner.com I think they are sponsors here and maybe you can get a deal by mentioning your a member here. I don't know for sure, but that's what I'm thinking, worth asking if nothing else. You might also want to post this question in the 7.3 forum as well, I'm surprised someone else hasn't posted yet with a 7.3.
