What should I tune on my 7.3?

Hey Guys!

I just picked up a '99 F-250, with only 170 miles on a 7.3L diesel, regular cab, eight foot box.

I've done a K&N cold air intake on it already. What else can I do to get more horsepower and torque?

-Magnaflow exhaust?
-Ramping, stacking the CPU?
-I wanna keep the stock injectors.

I want the truck to operate more effortlessly, smooth, and free flowing.
I still wanna keep good fuel mileage.
By the way, I haul a thousand pound welder in the box all the time.

Thanks!
Welder Dude.

Put a diy intake on it instead, make the exhaust free flowing, get gauges, a valve body, and custom tune it. You can't stack anything

I made my Samsung SGH-I997 send this.

If you want that truck to last, stop modding it and start reading up on it before you continue.

K&N will kill the truck and you can't stack chips. Start with the basics, a intake that actually filters out dirt, exhaust, gauges and a chip from DP, TW, PHP, etc.

Read read read! So much information on this site it's crazy. K&N is garbage! you know mangaflow from gas engines? If you are doing a straight pipe, there are a lot of options, many cheaper then mangaflow.

DIY air intake, straight exhaust(cool lookin' tip), high pressure oil crossover, and tunes. I love my php tunes. Also I have the fuel rail crossover didn't notice much but I'm sure it's helping. Edit: also gauges for sure.

Why will a K&N cold air intake ruin my truck?
What does a DIY intake do that's better?

For guages, Banks for turbo boost, trans, what else?

What brand of high pressure oil and fuel crossover lines do you guys recommend?

A four or five inch exhaust? What brand?

You guys know so much, thanks for all the help, much appreciated!

the 6337intake is really popular. You can find it on riff raff if you want a kit. They also have the high pressure oil crossover and a regulated return system for the fuel. Thats what im getting.

Auto meter, and ISSPRO are pretty popular. Glow shift arnt bad if your on a budget as far as gauges go.

MBRP makes a pretty inexpensive exhaust. Thats what i have and i dont mind it, dont have any expirence with any of the other ones though. Sizing is up to you 4inch should be plenty, 5 will get you more sound.

Alot of people have reported their K&N's letting dust through and "dusting" their engines. There are a bunch of threads on here, google "powerstroke.org k&N intake" and you will read more then you ever want to about it.

I have a k&N on here, came with the truck, no idea how long its been on there. Pulled the intake off and had no signs of damage to the turbo or residual dust on the inside of the intake. Most hate the k&n, some like it and swear by it. Personally im switching to the riff raff kit and using the k&N tube , why even risk it.. The kit is like 60 bucks or something like that.

Pyrometers are very useful, and help prevent you from working you truck too hard.

Possibly.
Read man. Filters better, flows better.

Banks? Made of money?
Autometer z series for me. Boost, trans, egt.

I'd only get a solid HPx line. Strictly Diesel.
RiffRaff makes the FRx.
