What's the single best mod for a 5.3?
I just bought a completely stock '02 Sierra extended cab 5.3 2WD. I will be using it to tow my race car this year on an aluminum open trailer with a large storage box (car and trailer weight about 4500lbs.). Most of the tracks I will be going to are about 400 miles from my house.
I don't have a lot of money to spend on the truck, but I'd like to do at least one thing to improve the power and/or mileage that the truck will get. What are some of the single best modifications that I can do to this truck to improve power and/or fuel mileage?

you're probably going to see the most gains from some sort of FI. Magna or Radix seem to be the popular choices for something you can do with out a lot of extra work. I think doing a turbo setup would have too many variables for you to iron out to get worthwhile power out of.
or you could do a TC but don't go rediculous with the stall rating since you're towing a heavy car

If I read your post correctly you don't have a lot of money to put in the truck so I would guess that would eliminate a turbo or SC. That being the case then a tune would be your best bang for the buck. Intake and exhaust catback will buy you very little on a stock engine. Get a 93 octane tune from one of the sponsors on the right---------------------> and you can do intake and exhaust later if you like. A stall is not the best for towing and may limit the amount of weight you can tow without worry.
