You use the brakes lightly too much. A couple of heavy braking stops usually will clear that up.
Yup, that, or a couple hard stops in reverse to break the glaze in the other direction.

Please don't put your reply to a quote within the QUOTE tags.
Put it after the last tag.
Makes it a whole lot easier to read.
I saw that AFTER I hit “send”
Tried to change it... no provision. Sorry

They are ceramic.... they don’t glaze

How much is your truck smoking? My stock intercooler blew out the passenger side which took my boost and made the truck less efficient. Wasn’t smoking that much until my exhaust manifold broke #6 studs. Fixed that then found my intercooler leaks. Make sure your boost pressures are good. Just my 2 cents.

Ya, I prob do press the brakes to lightly. The exhaust is so loud, that I instinctively feel Im pushing the truck hard, so I rider her pretty easy.. and yet still get 15mpg. I have tried pressing the brakes hard a few times to see if it helps take the squeal away. Maybe Ill try a little more. And in reverse, I can give that a whirl to ease the squeal on the ceramic breaks.

@FXDWG
So, my cermaic brakes need to be a bit warmer to help reduce squeal? Ya, that sounds about like what Im experiencing. If I get around to replacing allll the pads, Ill swap with the reybestos semi metallic pad for my cross drilled rotors. Do you think I need antisease on backing plate or is it the ceramic pads squealing?

@TxJuggernaut69 @Chrome
My 06 5.9 almost never smokes, prob cuz I drive it easy because of loud exhaust. If I put my foot into it, itll smoke plenty. Ya, I need to check for boost leaks for sure. I know, on an immediate steep hill, it seems like forever before I start climbing, but its just my slow foot and the laggy turbo I suppose, but i suppose it could be a small leak. Sometimes I feel like the 5.9 doesnt have the power it should. 300hp for a 7500lb truck doesnt seem right to me. Hopefully the air cooler doesnt have any issues cuz those are EXPENSIVE! But yes boost pressure seem to be accurate enough for me. Putting my foot into it, the EDGE has said 50psi. Normal driving through neighborhoods Im at 0 to 7psi. Are there any best ways to test for intake leaks?

@Chrome
Youve towed 20k ish behind a 5.9 2003? Wow, and did you ever have issues? How high would your trans temp creep? EGT? I've been wondering if I should upgrade the tiny trans cooler while Im replacing my A/C condenser cuz ill be pulling a 5th wheel eventually 2k miles. Do you think it's necessary? Maybe Its not because I find almost nobody talking about it, to help save the trans.

So, what do you guys usually get when you're loaded? Full load of dirt in the bed? 10k trailer mpg? Does it get down to 10mpg and worse?
It could get down that low, given the conditions you're towing in. But the truck does well in between unloaded and full capacity. That is where I really like living with a diesel truck. Where people are struggling with a gas engine to sustain speed AND get decent trip mileage, my truck is comfortable and right at home.

An example for me, loaded w a 3 rail motorcycle trailer, 3 loaded/fueled dual sports, a truck bed and cab full of gear, coolers and a friend = 14.7mpg towing from San Antonio to Alpine on the way to Terlingua. It was highway miles I10 truck cruising at ~72 = 19-2000rpm. Unloaded at the same speed from Terlingua to Alpine the truck got 16mpg.

As for a cubic yard of dirt in the back, done it several times but I haven't traveled further than several miles with that which isn't near enough to find mileage.

I've got a trip coming up out to West Texas again, will be towing a uhaul 6x12 cargo trailer to help someone move. The truck will have had fresh work on the both diffs, axles, hub assemblies, ball joints, suspension and alignment. So I'm very curious how much those factors will influence mileage, if any, for the stretch of highway and the conditions it normally runs.

I tend to pit stop every 2-4hrs. I'm the one that needs the pit stop, the truck is usually fine and predictable for fuel.

Maybe I should get rid of the catalytic converter if its in there? The truck has dual catback exhaust, but I believe theres what looks like a cat on this 06.
I wouldn't mess with the cat, you don't really gain anything. What size are the duals that are on there?

I always use antiseize, not for its noise reducing characteristics, but so the plates and slides work properly and release as they need to. Your noise is there only because your parts dealer failed to provide you with the correct parts.
I drive 350-500 miles daily in a peterbilt 389.
it has semi metallic raybestos style pads, and they never make noise. Some “wise guy” sold me ceramic pads for my wife’s daily driver once, and I was changing them out 2 weeks later with semi metallics.... I thought I’d never hear the end of it....
Lesson learned. Passed it along.... your welcome

wow 14.7mpg highway pulling and loaded. that sounds fantastic! I suppose I may expect something similar if we had flat roads, but were in the mountains.

06 5.9 dual exhaust is standard it appears. Id assume 2.5 each. Id be happy with a quiet truck lol. Im old now! I use to enjoy the extra power and sound from my racers, but not a truck.

@Chrome
Well all I know is, if I punch it, Ive seen the EDGE display 50 psi for a moment. Goes high fast. Maybe the EDGE is not so accurate too lol. Its old school. edge evolution screen with edge EZ module for 06 5.9. I do not notice anything when I turn up from 1 to 5, but I really havent tested to see what it feels like. I just drive the truck like a minivan.
The guy I bought the truck from was very upfront. I still text him with questions etc. He provided some receipts couple days ago even tho i bought it like 1yr ago. Poor guy gave me his number. However anything could have happened really. Hes had the truck since new, and he has a son, sooo you know country boys. Reports online show good from dealers. Underneath is quite pretty, no sludges, drips. Was garaged he claims for years, and it def was apparent because of the incredible appearance, yet still had old school decals. Its good to know she can pull the hills with her 600ft torque to get some trailers where they need to go.
Do you have a prefered MAX weight to pull? I know it claims to pull 20k but, up hills? 06 is an old truck. Seems like 15k combined would be smarter. I guess it depends on terrain really. ty

@FXDWG
Thx for the info. Ya, the owner said he had just rebuilt the front end and replaced all rotors and pads with ceramics. ALL MOPAR. So, I thought, well thats a plus at least. But ya, I may swap the pads out for met raybestos style if I ever have time. I like the idea of not squealing! lol
I wonder why he decided on ceramics? I think the truck sat in garage a LOT.

We are talking about a 5.9 Cummins, not a 5.9 Magnum.

Not even close.

5.9 Cummins Turbo Diesel inline 6 cylinder
5.9 Magnum Gasoline V8

Both approximately 360 cubic inches

All good points.
i swapped out my emissions cam shaft for a Colt stage 3. The engine pulls like a freight train, from 1600 RPM right to 2800. Pulling my 15,000 LB toy hauler, I now get 14 mpg, as opposed to the 10 that I got before. Empty, I lost 3 mpg (20 down to 17)..... I tow only 10% of my annual miles. I’m happy, but economically it was a bad choice

good tuning should gain back that 3 mpg loss you see empty...

I’m working on it. I have a smarty Touch, and I need to call them for some mapping. That cam may need a modified map

You think a good tune could help with mpg? You mean a dyno tune or just plugNplay? I only have an old school EDGE Evolution, so it may not be worth much, but I don't feel like buying a $1k item to save mpg lol.

Yes, as my sig says, 06 5.9 CTD RAM. Those V8 gas are horrible with mpg.

What do posts #26 & #27 have to do with this topic
Turbocharger operation. The pressurized air is maintained (boost) and is cooled before induction.

No boost — or INCORRECT boost pressure — means fuel delivery wonky. Too much fuel to do same work at reduced HP/TQ.

No tuner or programming will improve steady-state MPG. It’s otherwise a crutch for failure to adapt to what the truck is telling you.

Call up MADS as I did. They can’t do it, no one can. So it’s best to leave programming alone: Tires — and driver — are enough with a dead-stock truck maintained & serviced to schedule as the only “tuning” needed.

they are not going to help you get that done, thats going to be on you. Go look up the HP Tuners Lessons Learned thread, there is a link in there that talks about tuning. The key there is the LPP. Get that right and your truck will shine.

HP Tuners is far less and gives you data logging as well. Worth it for the weekend tweeker.

That is incorrect. Timing is everything. I can go dump 0.25* of timing on 2 of my timing tables and have a total dud of a running truck. Timing is so key to a good running truck it cant be stated enough. Next up would be the AFR...

Recent fuel receipt... I milked it like a farmer to get that 23 but its the only way to get consistency out of it to know if things are working right or not.

Oh definitely on the terrain. I can see the mountains taking more fuel. And those unchangeable factors being the case, give yourself every advantage for efficiency, like good driver inputs and sound mechanical/programming/equipment. Look into your tuning, that may be where you can find some gains, assuming good driver inputs and truck is sound.

For the exhaust noise, drop in a good 4 or 5" quiet system. It'll flow as it needs and keep the noise down.

If you use steady throttle on inclines and let your speed drop some relative to what it was on the flats, it will definitely help. On the decline if you can be off throttle at all or in neutral it will definitely help. With the subtle aero mods on mine, I can coast farther under more conditions than before the mods. The faster I go, the more effect the mods have.

Last road trip, 300+ miles speeds 70~75 mph, AC on for the return trip (heat wave weekend on west coast) and still got 22+ mpgs. I would bet I am over 20 unloaded doing 80~85 mph. Have a very similar road trip Saturday, temps are not going to be nearly has high but IATs should still be up there into the upper 80's and beyond. Will see how mpg's turn out as it will be a DGAS tank.

Oh I remember hearing the lies of 25mpg that led me to buy my truck. I'm living that 13-16mpg life.
