Well I was on a 500 mile trip trying to measure mpg's with my new injectors and the Smarty set on SW3. Lost my lift pump at about 250 miles into the trip and had to be towed in. That messed up the mpg test. After the repair I ran the last 250 miles and got 21.6mpg (hand calculated). I am still planning to go to the next higher smarty level for the trip home to see if there is any further improvement. This is not a true scientific test but I am seeing a nice increase in mpgs for my driving style.

Thanks for the kind comments hexOrz.Good luck with the install.

Sending you a pm about my injector story.

One of my problems is that there are so many choices with these tunes that it seems like it will take forever to try every option. Thanks for your input. I will get there and try this one also. - - - Updated - - - Didn't even know this site existed. Thanks for your input.:thumb1:

I recently put in a set of new Bosch injectors with 50hp DDP nozzles on my gen 3 truck.Monday I drove to Vancouver Washington and set the cruise on 65mph. A total of 426 miles one way.The Smarty programmer was set to completely stock. My plan was to drive one way in stock format and then do the return trip with the smarty 30hp + tune.So Monday I set off on the trip and everything was going fine until I got to the Columbia River gourge. Got into a head wind until I hit Hood River. I have no idea what the wind speed was but it was enough to make my truck work harder to keep the cruise speed up. That messed up my plans for a nice fair weather test.Hand calculated the fill up in Vancouver and I got 19.3 for the trip up. The overhead read 20.3.That's the closest to reality that my overhead has read since I have had the truck. Last tank of fuel I used before I changed my injectors had the overhead reading 4.1 more mpgs than the hand calculated actual numbers.Came home from Vancouver today and this time in reverse I have the Smarty 30hp + tune with timing on 3, TM on stock, RP on mild and waste gate off. Cruise control on 65 and and no wind on the return trip.Hand calculated mileage was 21.5mpg. And the interesting thing was my overhead read 21.4. :hyper:Of course I am thinking that maybe the mpg will go higher as I play around more with the smarty tunes to see if there is one my truck likes even more. :pray:I am traveling to and from Corvallis in the next two weeks (approx 500 miles each way) and I am going to try to two different tunes to see if I can see some increase. Of course these are just a sampling of very basic tunes but I am going to try 60hp+ one way and then the 90hp+ on the return trip.Did I say that I was pretty happy with the results so far?

You can buy a gallon of the Rhino type liner material. I know a person that put it on his rockers himself using the small 2-3 inch wide paint rollers. Taped a line (using paint line tape) and rolled from the bottom of the body up to the tape line. He prepped everything (cleaned and degreased and scuffed up the paint). Don't really know how much time he had in it but he finished it in one weekend. I thought it looked really good and that inspired me into thinking that is what I want to do some day in the near future. He left it the black color and it was a nice contrast look.

Make sure your spare is good and aired up.Have a good trip.

I went through ND last year in the summer time and there was water everywhere. They had some of the freeways sand bagged up to try and keep the water off and had many gas driven pumps running everywhere trying to move the water away from and off the roadways.I have seen water over the roadways like this in other places like Texas, Louisiana, illinois, Indianna, Florida, Oregon, Washington and Idaho. But didn't expect to see this in ND

I have never even seen those things before.So they keep gravel from being thrown up and chipping your paint.:thumbup2:I have seen some folks actually paint the lower parts of their side panels with bed liner paints. (up the whole area where your silver paint is.) This stuff is pretty thick and rugged. Then they have painted a finish color over it so it doesn't just show the black color.I don't know how this approach would compare to your solution but I have though at times that I might be interested in applying the bedliner approach to keep the rock chips in control.

I don't have an EB so I am not speaking from experience but just thinking about it. When you are pulling something heavy and want to use your EB to slow you down it has to work against the load you are trying to slow down and the velocity from which you are trying to slow it down from.As you may know the transmission mutiplies the torque output of the engine and has to be strong enough to handle the output torque of the engine.So when you are trying to use the EB to slow down your truck with it's load, the transmission has to be able to handle the reverse torque of the load you're carrying and the speed from which you are trying to slow down from. As you go down in the gears (and up in the gear ratio) you are multiplying the slow down torque that the transmission has to handle in the lower gears. This reverse load may exceed the capabilty of some of the key transmission parts and break them. I think that is why transmission recommendations include recommendations on using billet input shafts and someties other key parts depending on the torque requirement the transmission may be required to handle.

I did the mod using the Flex-a-lite fan assembly on my gen 2 truck (back when they were $400 +).No mpg or performance benefit could be detected.If you are a heavy puller then you will also loose cooling capacity at the higher towing weights.Directions say to not install if GVW is 20K pounds or above.The engine is quieter because you don't have the noise of the stock viscous fan engagement.I can't identify any other benefits from the install.

X2. Now that the tranny is at least 90% good then what are you going to do in your spare time?

These are DDP nozzles and not Bosch Marine nozzles.I don't have technical specs to know if DDP nozzles are different than the Bosch Marine nozzles that I think you are referencing.The DDP nozzles were specifically for the '04.5 to '07 5.9 Cummins CR.The injectors were new Bosch (not rebuilt or remaned) for the same engine and not the Marine injectors.I have been told by several vendors that Bosch has recently made some body change to their Marine injectors that will no longer fit the aftermarket nozzles like DDP etc.

The nozzles were 7 hole design. The vendor provided me with the flow data and the angle of the spray which was for the '05 CR. I had not way of testing them myself so I relied on the vendor info.I have less than 100 miles on the new injectors so far. Biggest changes I have noticed so far is that I don't produce any smoke on acceleration and my overhead is reading different. Appears to not be as optimistic on mpg reporting as with the previous injectors.The last full tank of calculated mpg was off (low) 4.1 mpg from the overhead read out.

So do we have the tranny working right now?

Do they make nozzles with a smaller gpm flow that could be changed out easier and cheaper than changing out the pump?

Nice looking mirrors.. Gives a newer profile look to your truck.With that new bed on there you will have to rub out your cab so the paint looks as white as the bed.

Well today I changed out my old injectors for the new Bosch injectors with 50 hp DDP nozzles.I didn't have anything too serious to complain about with regard to the stock injectors with the single exception that my truck was smokey when ever I would accelerate. The harder I pressed the 'go' pedal the more smoke I made. Even when using my Smarty, I just couldn't minimize the smoke. Now i didn't black out the area but it would certainly leave a noticeble cloud when I would accelerate.So no missing or other noticeble problems. I have 128k on the original injectors.So the motivation for the change was strickly hoping to get a little better mpg (and performance when needed) and I got a very good deal on the injectors so I bit the bullet.:think:I was surprised with what I found when I got the old injectors out. 4 of them were wet and very gummy feeling on the nozzles. The other two were dry and pretty clean looking. One of the dry ones was clean enough that I could read the nozzle information that was etched on the side of the nozzle. The other dry one had a lite coating of baked on carbon, but I could sort of make out the etched markings on the nozzle. The 4 wet nozzles were so gummed up that you couldn't make out any markings.So my initial take away is that I had 4 injectors that were weeping (or maybe leaking). I am still perplexed why I didn't have some more noticeble tell tale sign that 4 injectors were going bad.After the injector install, I drove the truck and I couldn't make it smoke. I have the smarty set to stock right now. I am hoping that I will in fact see some MPG improvement now. I will drive without the Smarty for a while until I can characterize any improvement just from the injectors then I will play with the Smarty to see what further improvement I can see.

I thought about saying something like this:"This was a test to see if anybody was reading my posts".:sleep:But alas, the better part of valor (bold ___ lie) wouldn't let me do it!:evilgrin:Oh, by the way, you passed.

Good eye! I think you are right.How about these. Feeling any better about it now??

Looky, looky at the new Bosch injectors and DDP 50 hp nozzles I have. :drool:

Hex0rz:Here is a picture of the mounting system for the SuperGlide rail mounting system for your 2nd gen truck.It includes the 4 mounting brackets, the hardware packet and install instructions. All brand new and unmounted.

The new bed adds to the look of your truck.Not to hijack this thread but did you get the new ECM installed and did it help fix the tranny issue?:pray:

The ride means you pay the shipping to get the parts to you. This manual shows you the mounting system you need for your hitch. If you look at page 9 you will see the frame mounting kit that I have. It is for the SuperRail system and this manual shows the frame mount is the same for "95 to '02 trucks. http://www.pullrite.com/pdfs/3346.pdf
