I've been doing a lot of searching and am having problems finding direct answers, so here are my questions. What is the best route for fuel economy and bang for my buck with cold air intake (AFE/K&N/etc...) and exhaust(4"/5" & Brand)? I plan on keeping the motor and turbo stock.

What is the best chip/tuner for fuel economy and durability? I keep seeing SCT when doing searches and have no idea what that means. My truck has the edge juice (ejf2000) on it right now since I bought it with that already installed. It sounds like they are pretty much junk, so what do you guys recommend. I do plan on towing a camp trailer.

Also please keep in mind I'm looking for the most bang for my buck when buying exhaust, intake, and any chip/tuner. If you can give me suggestions on where to find these parts or where you would recommend I go to buy them. I live in the middle of nowhere in Oregon so internet stores would work best for me.

Thanks so much for any advice.:confused:

I have custom straight exhaust (turbo back = 4" down pipe - 5" inch out). MBRP makes a nice fitment, if you are going the online route.

I had the Edge w/ Juice....made nice mileage, but I think in the long run led to problems, thanks to my guy (Stauffer Diesel) and now talking with guys on here, the only option for a Ford is SCT programming with custom tunes. I am sure the guys on here can send you in the right direction for your tuning. It will be customized to the modifications you have made to the truck.

I am running a True Flow XDi Cold Air intake. I like the setup, but am eventually going to get an Amsoil Cold Air Intake (someone makes the setup and they brand it).

In all honesty, the biggest jump in any fuel mileage that I have seen came immediately when I put Amsoil 0W-40 Severe Duty in the truck. It was an instant 2 mpg.

In summary, SCT X3 programmer with custom tunes, tuning will get you where you want to be.

Your factory intake is fine, nothing filters better than it and it isn't going to give you a huge bump in performance to change it out.

Exhaust is pretty much exhaust. Pick what size you want, most go with a 4" or 5" system with a 3.5" or 4" down pipe. I say get whatever you want for a price you're comfortable with paying.

The SCT stands for the SCT brand flash tuners such as the X3 and X2 or livewire. Basically it allows someone the ability to write custom tunes for your truck. The edge is junk, just raises cylinder pressure and trashes transmissions.

Head over to innovativediesel.com and talk to Eric. Send him an email describing what you're wanting to do with the truck, what you're hauling, what power you're looking for, etc. He'll set you up with whatever you need.

Thanks for the recommendations. I'll definitely get in touch with Eric at innovative diesel for the different tune options. Is a 4" or 5" exhaust going to be better for fuel economy and power on an all stock motor? Or does it really matter? Does downpipe size make a big difference and should the downpipe be the same size as the exhaust or a size smaller for optimal performance and fuel mileage? Sorry about all the questions my learning is just now beginning.

X2!!

I have a 4 inch exhaust it is more reasonable and flows good enough. I bought an Air Raid drop in filter and still run the stock system. The reason for the Air Raid filter is the cost of the Ford filter. I get 18 to 20 mpg hand calculated. But my truck is 2wd.

like stated before get the exhaust you want at a price you want most go with a 3.5 inch down pipe because a 4" is a tight fit and hard to get into place. Inovative has some great tunes. your stock air intake is good for about 500 HP. alot of people have problems with the head gaskets blowing so it might not be a bad idea to save up for some studs and if you have to do that an egr deleat woldnt be a bad idea I know you said you want to keep the motor sock but those are 2 mods that I wold highly recomend to any one with a 6.0 and are the 2 most common failures with these engines

What exactly does an EGR delete buy you for durability? Approximately how much will it cost to get the better studs and EGR delete done by a shop that knows what they are doing?

egr delete gets rid of the headaches that are associated with the egr system. as far as exhaust I bought a 4" set up from summit racing for 300 bucks. its summit branded but as far as im concerned exhaust is exhaust. It fit great and was cheap compared to most name branded exhaust. If I was to do it again i would have left the stock down pipe in. it was a pain to get the 4" down pipe in.

What would you recommend I do first? Exhaust, EGR Delete, SCT X3 programmer with custom tune, or head studs?

I figure the EGR delete is probably first, then exhaust, followed by the custom tune for fuel economy and towing, and ARP head studs if I ever have issues with my head gaskets blowing.

Does that sound about right to everyone???

Also, can anyone walk me through the removal of the edge juice. I notice it is just spliced in to a couple of wires and it has a line running down to the exhaust manifold on the drivers side. Can I just disconnect all of the connections or are there oem pieces that were removed for the juice installation that I will need to put back in place.

I only have the edge juice. There is no monitor installed. Should I be concerned about anything with my engine or tranny since the previous owner had this installed? It runs real smooth compared to the other 6.0's I test drove and the A/T shifts strong and smooth.

Thanks again for all the help!

I did exhaust first, then air filter, and finally sct with custom tunes. Let Eric know you have not done studs yet and he'll tune for it. I haven't had any problems yet, but I am pretty gentle on the go pedal and don't abuse truck at all. Been this way for about 15 000 miles. Custom ficm next and possibly Doug' s tune next. Egr delete in the future.

if I could afford it I would do studs and an egr delete before I did any tuners. that way hopefully there would be less of a chance of something breaking. I know there is alot of people out there that are running SCT's that are not having anyproblems. I think it all depends on how you treat your truck

I have a stock boost gauge, so do I still need to get an aftermarket one that goes to a higher psi?
not really its just more convenient to have all the gauges in one location when you are pulling on it hard. not having to look in multiple locations is nice but your factory gauge will work fine if you dont want to buy another boost gauge.

Hi, I'm new also, I've read alot of the threads and learned a great deal. I have a 2003 6.0 Excursion I bought used 2 years ago. At the present time my truck is at River City Diesel getting egr delete and head studs done. First question, has anyone had this done through an aftermarket warranty company (mine is Auto Service Company Inc.) and how did it go, any problems or hassel ? Second, while the body is off would it be easier to have the exhaust done (3.5" or 4" downpipe)? What modifications need to be done to fit a 4" down pipe on compared to a 3.5"? What is the ficm I keep reading about and what does it do? Thanks for any input.
