Just a few questions. I have been thinking about buying a chip to help out when I tow. I have an '02 f250 auto with 4" turbo back exhaust and the Tymar intake conversion running on 100% homebre Biodiesel. I regularly tow a 5000 pound boat and was wondering what you would recommend for programs to get. I dont run out of power but maybe a little more economy or something to get the tranny shifting firmer is basically what I am looking for. Besides, it would be fun

I was thinking about the following:
80 econo
80 tow
high idle
stock
valet
and MAYBE the 100 hp setting.
Would these be good selections for my application? If not what are your suggestions?
