Help with deciding
 

Looking at the Phoenix Chip or the FU
Diesel Site.com told me to go with PHP (KOODOS to Diesel site) Bob Riley.
Truck has the following mods:2000 F250 Crew Cab 4x4
Full exhaust 4" with 4" down pipe,no muff
K&N air intake system
Wicked wheel
sonax kit in the tranny
Adreline oil pump from Diesel Site.


I tow a 30' tag along trailer with race car and gear.Not sure of total weight i would guess around 7000lbs.
not much of anything else, the occasional flat bed trailer with the lawn mower.truck is my daily driver . Truck has 3.73 gears, riding on 35" tall tires.
I do drive the truck out of town sometimes, not towing , I currently get 13mpg driving back and forth to work. Around 16ish(mpg) on the highway not towing. Towing the race car trailer I get 9-11mpg depends on how heavy my foot gets, usually riding 75mph.
Would like to see my commute back and forth to work MPG go up.

currently using an OLD superchip 80HP tune.

suggestions please.
Thanks,

An OLD Superchip tune huh? It might be one of Bill's anyway!

Bill can definitely hook you up with what you need.

anyone have any suggestions?

With the Phoenix you get 6 tunes, with the sale about $320. The FU you get to change as often as you want, but that is $465 with sale. I went with the Phoenix because I didn't see the need for changing often. Besides if you want to change the Phoenix send it back for diff tunes.
