currently have an 02 f250 with a 7.3litre turbo powerstroke and am very curious to why this motor is considered not to respond as well to the power programmers and chips as that of the 6.0litre power stroke, 5.9 cummins 24v, and 6.6litre duramax. Can someone actually explain the differences to me? I'd imagine it's something to do with the fuel delivery system of each particular application and the variable vein turbo's on the duramax and 6.0 litres.
General Questions about 7.3 and other Diesels?

100 hp with a chip seems not to shabby to me?

Don't get me wrong, I love my power stroke, but it just seems that some of the others really really respond to simple stuff. For instance the duramax in PHR that had a tune, converter, alison upgrades, and exhaust and went 12s in a 6500lb standard cab chassis.

I would love to know more about your truck, your signature is not filled in do you have any mods.

Sorry for the late get back, was out of the office. My truck is an 02 250 4x4 crew cab short bed. Got it with 130,000 miles on it in which the guy before me had cut the muffler out of the stock exhaust and put a tip on it and I'm pretty sure there's a program in the truck. It runs way stronger then any of the 99s or 00s that I drove unless that is something that just happened in 02 (did anything change at all between those years except for the fact that I got the crappy rods)? The salesmen I purchased the truck from also seemed to think a program existed in it. Since then i've put a 4" jegs turbo back on, a stage 2 AFE intake in, warn premium hubs, and put a tri cumulator spring and sonnax vavle in the 4r100. I'd love to know how to find out what program's in this thing but know one has been able to answer that question thus far, that is ofcourse if there is an actual program in it. I tow a 5000lbs trailer with my car on back (big reason for this trucks purchase) and am very happy with it, but have gotten whooped by a duramax before and understand in general this one isn't the one to modify and was just looking for reasons why, that's all.
I'm completely brand non-loyal as my car is a 01 camaro ss with a 434 c5-r headed motor. I bought the 7.3 cause it was in my price range and have heard nothin but great things about it as far as reliability and it's ability to pull things. Things i'd like to improve include mileage (get about 12.5 around town and 17 on the highway according to the readout in the ceiling) and make it a bit quicker. Looking for cheap things if possible as the camaro project is my money hole, ha /ubbthreads/images/graemlins/cool.gif Any suggestions are appreciated.

have you checked the PCM to see if a chip is plugged into it??

Is the pcm under the dash on this truck? That maybe something to look into. I'd think there would be a switch somewhere if a chip was installed but I suppose you could get a single position chip as well.

the PCM is near your left foot while driving. There's a cover over it although I don't keep it on mine. I've got a chip on my PCM (no switch) Once you can see the PCM, there's a place on the side where you can plug in a chip. Look to see if there's a small (about credit card sized) object plugged into it. If not, then check if the terminals look like they have been cleaned. That would indicate that a chip HAD been there.

Thanks for the tip! /ubbthreads/images/graemlins/cool.gif Will do!

Nick - I don't see anywhere that you have gauges??
If you plan on "hotting" it and towing - you had better allow for Tranny, EGT & Boost gauges.
[/ QUOTE ]
You're right, I don't have any. I've just tried to use common sense as to not push the truck to hard during any extreme load situations. I'm on the eastern shore of maryland which is as flat as it gets so I don't have to worry about reaaaaaaaaaaal extreme loads but need to get some gauges sooner or later.
BTW, are there any free mods to do to this thing, such as waste gate modifications to get more boost and do so safely (ofcourse once the boost and EGT gauges are in place)?

you don't really want to do that. you'll blow up your turbo. that's what i do when i try to blow up mine, but it hasn't worked yet!

Ha, I figured there was a downside to something so easy. Oh well /ubbthreads/images/graemlins/smile.gif

You can unplug the red line on the turbo and just put it on an intercooler tube clamp. that will plug the wastegate if i'm not mistaken. There's also something called the 10k mod which you could do a search on but my understanding is that a custom chip is the best way to go. while not cheap, it's worth it. check out some of the sponsors. I have a DP- Tuner 4 position chip. Not to beat a dead horse, but make sure you get gauges if you have a programmer or chip; gauges are useful even if you don't have a chip.

dirtymaxes and cummings can make more go then teh ford 7.3's.
the ford motor is tough, reliable, and torquey, but for ultimate power they won't keep up.
tymar is 100 bucks installed for a free flowing air filter.
dp is about the best chip.
after about 120 horsepower, yhou have to spend BIG money to do anythging very useful on the 7.3's.

Thanks guys for the help and suggestions thus far. It really seems the duramaxes can make a ton of power with simple add ons as well as the cummins, but that 5.9 seems to need a little more help in the form of turbos and such.
I was just curious to see if someone could explain the differences in the motors to me as this diesel stuff is quite different then the gas motors i'm quite familiar with.
I bought this truck for pulling and durability so it looks like the 7.3 has done quite well in that area. Just hearing all of these other's making such and such power etc. etc. is driving my interest up in modifying it though. Sounds like once a dp chip or some other tuner I add to this thing then it's done without getting serious and as i've said one money hole is enough. Still not sure if this thing has a chip and after reading Diesel Power where a stock truck just like mine ran a 16.60 or something at 80mph it seems these trucks just run a little better then I thought and I don't have a chip or programmed computer.
You guys with your chips and programmers, when you floor it how much smoke comes out? Is it really thick or just a slight shade? I get more of a slight shade.

It totally depends on the program. Some tuners will put out very little if any smoke, others, such as the Dp on my truck roll it out like an overloaded freight train.
Here's a pic of it smokin on the dyno GAM Dyno Day Smoke
Don't think you can 'just' add a chip and not spend any more money, trust me, it won't happen. It's all interconnected and stock it is a reliable unit, you change one thing such as the programming, and be prepared to change a whole bunch of other stuff to make it a reliable unit again.
Gauges ...350-450
Exhaust...400-750
Intake....100-500
TorqueConv500-1200
Tranny....3-4000
Turbo Surge.400+
There's much more, and some quick math will show you it's not cheap.
...and yes, you WILL need to address every item listed sooner or later if you start modding.

Exhaust and intake are taken care of. Just ordered a chip and will add gauges shortly. will be very easy on this thing until I can monitor things closely and understand that if I pound the living daylights out of it the tranny and converter as well as turbo will be history in no time. Hopefully the economy tune will help my mph which is about 60% of the reason I ordered the piece!
