Was wanting to get some feed back on what are some of the best performance enhancements available for a 2003 7.3L. I have owned the truck since new and it has been exceptional. Truck has 190k on it, all stock. I want a little more power to pull a 44ft gooseneck enclosed trailer, but I don't want to hurt the reliabilty that I have had with the stock motor. Any feed back would be greatly appreciated.

i had the exact same truck...

my suggestion is
intake system
turbo back exhaust
and a custom tuned chip like this Tony Wildman Performance Chips

you may also want to do a trans cooler upgrade as well to keep your temperatures down while towing

if you have any questions please feel free to PM me

For you, I'd do all of what he said, in addition to a valve body and an external spin on trans filter, if this is an auto trans.
Then of course there's all the maintenance things to take care of.

Like stated above, intake, exhaust, gauges, and tunes are a great starting point. It will definitely help when it comes to towing as well.

We can also get you setup with the products listed. Contact me if you need any additional information.

With the miles you have and the size weight your going to need to start fresh as your Inj's and trans have seen better days and towing heavy gona kill them leaving you stranded...

here is what I would suggest if you want to have a great towing rig and not brake down, its not cheap but neither will be the costs when you brake down.:

31 row trans cooler
Stage 1 inj's
BD exhaust brake.
AIS intake kit
4" turbo pack exhaust
RR fuel system with fuel bowl delete.
new UVC's and Glow plugs.
910's valve springs.
TW custom tunes
