So I get the 7.3...

and now for the real questions...

I bought to use for Daily Driving (kid haulin) and to Tow our new Travel Trailer.

Of the 3 most popular mods..which should come first? Will do one at a time..budget!

Cold Air Intake
Tuner Box
Exhaust

I am interested in Exhaust...a single...but not interested in having my Cab full of noise that works on the ear drums, and the wifes nerves! Who make a Turbo Back exhaust that has the least in cab resonance? I am fine with the noise I have now (in cab) but nothing louder...out the rear is of no concern!

A tuner will be fine, nothing too fancy, but something to work with exhaust and CAI

CAI can follow the above guidelines...not building a race or show truck here!

I'm not into pulling or draggin' so no super power house is needed, just mainly want to increase Mileage and a pwr increase wouldn't be that bad either.

Very LTD budget here, but all advice welcome!

oh, and....
What about Bio-Diesel?
