Your opinions on Performance Chips (for trucks)

[Hajo]

There is an AIRRADE intake on it with 3"downpipe going into 5" strait out the back so I think it's all good with getting air in and out.

The torque converter was rebuilt about 5,000 miles ago.

If the above are modifications(larger intake and exhaust capactiy for the engine) larger then what was stock?
If these increases were above stock more then likely even though these were added the engine might not be taking advantage of them.
There is a chance the PCM doesn't know these mods were made unless it can tell automatically somehow.  Then the mods could be useless.
It may well be....and I say MAY that the diesel is saying so what!  If the PCM doesn't know there is the capability of more flow
it can't take advantage of it, there is that possibility.  The PCM,ECM whatever your manufacturer calls it MAY need reset to take
advanatage of the upgrade.  I'm no truck expert to be sure.  From experience I added an INJEN Powerflow intake system and a high flow
Corsa exhaust.  I reset the PCM simply by pulling a fuse for 30 seconds and then drove it like I stold it after installing the fuse of course
so the engine could take advantage of the incresed in/out flow. Pulling the fuse in my case reset the PCM and logged increased in/out capability
when I drove it after the reset.

I'm no expert on diesel trucks for sure but I think it may be worth the time to look into that possibilty.

You need advice from a true truck (diesel) expert!

I see what your saying there. I will have to look into the tunes, but I'm pretty sure there is tunes for the use of different air intakes.

What year 7.3?   Wide variety of options out there for 7.3's.    The first thing one has to decide is "what exactly is it I want out of my truck".    It is entirely possible to get upwards of 700hp+ out of one, but reliability obviously goes out the window at the same time.

Go with a tuner if at all possible, especially if it's a daily driver.   With more ponies comes heat, which to a point in a diesel is a good thing, but a bit too much is BAD!!  If your gonna up hp by more than 30% or so,  your friend will definitely want a larger after cooler and piping.   Banks at one time made several nice kits, spend "X" amount, and get "Y" horsepower.   The more ya spend, the more ya get.  I suspect the truck has a few miles on it now, has it ever had anything done to it up to this point?

Turbo kits alone for 7.3's did wonders, look into it.  Tell you friend to do his homework on this one, and he will have fun and reliability at the same time.

Good luck

Its a 2003.5 so it's one of the last 7.3 power-strokes made.  It has ONLY 45,000 on it and it was a Texas Truck (lucky arse) but he wants a daily driver with alot of get up and go.  I showed him Banks website, but he doesn't understand how anything works or what it does. lol

Get his questions and post here, or pm me.   Will be glad to answer/ give advice.   7.3's were the beast of the ford/ navistar V-8 diesels.  We can get hi pointed in the right direction for sure .

I have a bullydog tuner on my cummins isx 600.  with  just the tuner and going to straight pipes  was able to bump the hp up to 830  and the torque to 2650. I've got 832602 miles on the engine with no problems. isn't there a bullydog shop in port huron? seems like I've seen a billboard on I-69

It completely depends on what you want out of the truck.

If you want to go fast, get a car.

I just went thru "chipping" with my 6.0 Powerstroke. The first place to go is the FTE forums, that place is a goldmine of information from Ford techs and owners. One of the first things I found out was Bully Dog isn't very popular because it will trash your transmission. It doesn't make adjustments to the tranny for the extra torque being thrown at it. The 7.3 is different since it has less computer programming, but you need a programmable tuner like SCT (formerly Superchips) and a reliable tune that will adjust all the parameters in the engine and tranny. (After reading up on the 7.3, you won't need a programmable tuner. Everything changed with the 6.0)

I'm running the 8K Tow tune from Matt at Gearhead. It came highly recommended and I've been thoroughly impressed with the results. I also bought the Street Race Lite and Unlimited Tow tunes but haven't run them yet because I've been so impressed with the 8K tune. I weigh up to 25K GVW hauling hotshot with an '06 F350.

Bottom line is go to FTE and read up on your options from the experts before you spend any money. You'll be glad you did.

I liked it

FTE is a goldmine of info for Ford trucks. It has helped me pinpoint problems and plan what I wanted from my Powerstroke. If You own a Ford truck you should be reading FTE.
