I would love to have those pictures of @dripley in those places!

The last person I know that had axle gears swapped out from 3.55 to 4.10 it's rather expensive. Local gent in McCall ID did his for a sum total of $4,000 for both front and rear axles. This was fresh and brand new gears, bearings, and pinion seal. He's running 4.10 gears now with 37" tires and loves how his truck runs now.

Yup. That is the right action to take. I know the guys at Quadzilla will make it right. Most likely ask for the wiring and the module both to be returned just to be sure there are no electrical problems. Like, in the beginning, I had a bad harness and I had the option of fixing it myself or send it back for a new harness. I call Quadzilla and they confirmed what I found and yes I opted to fix it myself. Worked great. Call them up and talk to Quadzilla I'm sure they will fix you up right.

Like locally everyone wants everyone to buy locally. That's fine but when local prices are out of control. Example a metric set of Crows Feet. They want $50 bucks for a simple set of crows feet. Then check Harbor Freight... (Mostly China made stuff). It's $11 dollars for the Crows Feet set. I still bought the set locally and paid the high price but I should have just waited till I went back down to Ontario, OR and got the set for cheaper. Comparing prices between the two local set was 555% higher than Harbor Freight. What sucks I've never owned a set of Crows Feet for all these years and only needed them for this one job. So was the investment of the $50 buck for a one time use a wise investment? Most likely not would be better to buy China made Harbor Freight. @KATOOM you do have a point. I've got no problem with buying American Made stuff as long as the price is competitive not like what I was dealing with and paying 555% mark up for a locally supplied tool. That complete BS and unfair. Now if the selection was the USA made Crows feet for $20 buck and the Harbor Freight is $11 I would have jumped for the USA made for the $20 for sure. Just being made in America doesn't make it right to mark up 555% for the same product. Kind of like Dodge, Ford and Chevy truck prices are now gone out of sight. Then Toyota, Kia, etc are cheaper priced.

Kind of like Moog Ball Joints, Assassin Mechanical Fuel Pumps, and Smarty Tuners are all China made. Just a few off the top of my head.

That's the man I want to meet next. I've spent so much time on the phone helping out and listening to his troubles that I'm super curious to meet this man.

I have as well. Darting back and forth in the lanes couldn't hold it straight and completely failed in Downtown Boise. Lot of metal grind noise which was loud enough to hear in the cab with the windows up. Again another common failure for excessive use of the service brakes. The brake fluid gets hot and cakes up to the pistons in the caliper till pistons start to hang up. Which in turn creates the problem, even more, being the piston will not fully release the brake pads. You can prevent this failure with 30k miles brake fluid changes and limiting the use of the service brakes and lean more on the exhaust brake.

Yeah, who did you call? Seriously, this why I want to get the 911 area going again. There is so many member scattered around the US and Canada there is no reason why we could be able to lean on the membership pool here for support or times of need. 5,5xx plus members. Member Map 911 listing

I hear ya. Just like the VW vehicle over there in the EU are illegal to be sold here in the US. You guy have vehicle with way better MPG's that US has. There was a thread here on M73M where guy went to the EU for vacation and wanted to buy the vehilce he was driving over there in the US but it can't be sold or brought to the US because its too efficient. Being all US highways are based from fuel taxes and overly efficient vehicles would hurt the highway tax dollars. China has the worst emissions and air quality in the world. I've done some study on that and very shocking to see all the different device people wear to just breathe clean filtered air because of all the manufacturing and cheap goods. USA is so crazy about making vehicle less efficient. Go figure...

Like I learned from another member here might not get brake fade but just the heat of long downhills is enough to heat up the grease in the unit bearing and make them fail premature. Unit bearings are not cheap. At least in Idaho. We've got a few that as steep or more.

My MPG up being its expensive to travel 1,000 miles a week. I did like you Chevy DieseFuture just not a good daily driver that is for sure. It would kill me to drive that back and forth to Ontario. Out in the back country I bet that thing is a blast.

Funny you bring that one up. I've got my buddy in New Meadows that owns a V10 Dodge and parked it because it cost too much to drive. Loves the power but its a fuel hog. His is a 1 ton truck and more tires and does about the same for MPG's. Told him he should trade that for a Cummins or at least swap a Cummins into the frame.

Awesome Chevy @Dieselfuture. Still that is a lot of rolling resistance and drag. Takes a lot power to keep slinging those huge tires around even with good gearing.

Not really. When you figure like @JAG1 a set of units bearing in the front, rotors, calipers, and brake pads. Once you run a steep grade and you overheat the brakes most everything will need to be replaced for safety. JAG1 found out that the heat from the rotors cooked the grease out the unit bearings, warped the rotors, burnt the brake pads, and possibly doing seal damage to the calipers. Only takes one steep grade to do damage. Even better yet he wasn't towing. Just carrying his camper in the bed of the truck. $1,000 only covers maybe 2 sets of everything.

No, not really. Being you need the PCM to start the CCD network. You need the ABS computer for road speed signal. Without the PCM you can't read any error codes from the OBDII port. Without the PCM the speedometer won't work and the grid heater won't cancel for road speed. These are common issues with retro fitting 24V ISB Cummins. Once you isolate the ECM its a dumb computer and lots of other mods end up happening. Best to fix the existing problems that moding around the problem.

Nothing special here just the 3.55 gears, 5 speed transmission, stock 245/75 R16 tires on 16x7 stock steel wheels. This is what Dodge and Cummins designed the truck to run with. As for the quoted sweet spot we can't run that exact sweet spot for all speeds. The only thing that actually changed is I'm 5 MPH slow vs RPM. So I'm about 200 RPM higher for 80 MPH vs 235's / 265's tires. Which all all stock sized tires. My 66 MPH is a exact 2,000 RPM where before it was like 1,8xx roughly. Still running what Dodge and Cummins designed. I do like the rise in RPM it has been netting better MPG overall on average. Being I need less torque to keep rolling which can be seen in engine load.

Regardless... I came to the table with what facts that I can provide. No theories here, all post information was taken from the trip to Nampa and back to Ontario. The MPG numbers is posted from my previous trip to Nampa and back to Ontario. Again EGT's are lower, engine load is lower than most and making 19.58 MPG at 80 MPH. The part most I don't think are calculating is frontal area increase in lifts and larger tires. Then the rotational mass of the larger tires takes even more energy to keep twisting. Wind drag where a vehicle standing taller in the wind is going to have more drag. Like the OP installed a 4 inch lift, and oversized tires. For every 1 pound of rotational mass you can drop is like 8 pounds off the frame in rule of thumb. Again adds up to more drag. More about rotational mass... http://hpwizard.com/rotational-inertia.html Still got 3.55 gears, 245/75 R16 stock sized tires, 150 HP injectors (7 x 0.010 @ 320 bar), HX35/40 Hybrid Turbo (60/60/12), factory steel wheels (16 x 7), and my economy tune with some steep timing. No other magic here. Wheels and tires are what Dodge and Cummins designed the truck to run with. Like the drag coefficient on my truck in factory trim is 0.41. A one ton dually Dodge has a drag coefficient of 0.49. I can see a lift kit and oversized tires going up in the 0.5 to 0.6 realm adding huge amount of drag.

Your like @pepsi71ocean he's got the same front rotors too. I wonder if there is a way to just swap the unit bearing and be able ot use the later style?

Figure after the June 17th. I'll be done with all my hospital stuff. Thank you for the kind comments.

I've got a smaller turbo. (60/60/12) plus my injectors are 150 HP (7 x 0.010 @ 320 bar) so I require less fuel to spool up. Bottom end for mine is just slightly smoky but clean enough to keep big city cops off of me. Beyond that I built the tune to keep the wiretap high in the boost realm so you run mostly on the CANBus till you stand on it. Designed most for MPG numbers. You can bring the wiretap down in boost pressure and it would kick in quicker. That the beauty of Quadzilla you can have as many tunes as you want.

I made a rather simple spreadsheet to math out things and be able to visualize your settings a bit better. Here is the way I typically build. This spreadsheet allows to pick a starting percentage then build a offset ramp to your liking.

Sorry but yea. It was because the only 2% were donating and the other 98% where riding for free. We've got server bills and I've got my own bills with the hospital as well. When the income drops so low that its not covering all the bills before paying myself there is a serious problem and the site will end up closing. So now way lower rates everyone pitches in a smaller chunck but now will help in keeping the site functional and allowing me to pay my own bills too. I totally agree. I've never been that low even in Boise traffic.

Not all 53 blocks will crack as @cajflynn about his 1.3 million mile 53 block and hauling boats.

@dripley right on the money.

Typically drops low. My DiPricol did fail and was reading half the temp it should. Being that pyrometer problem is a bi-metal pair and creates a very small millivolt signal. As the probe fails the voltage drops. Some EGT gauge use a signal amplifier to boost the signal for the gauge.
