    Default Duramax Programmer Suggestions

    Looking for recommendations and or Pros/Cons of putting a programmer on my '09 Duramax. Just turned over 100,000 and I tow a trailer with it 3-4 times per week. It is a 3500 - 4x4 Crew Cab. Also pull a 30' tag trailer during race season.

    What increase in mpg should I expect?

    Thanks in advance for the info.

    The pros:
    - Cooler Egts
    - Better performance
    - Better mpgs
    - No more wasted fuel on regens
    - Better sound
    - Throttle response

    The cons:
    None

    My 2007.5 (Same LMM Engine) has the dpf and cat delete. Quadzilla Stealth II Programmer set at 70-90hp over stock. My truck is lifted on 35s and I get about 19-20hwy, 13-14 city and 16-17 towing.

    You wont get any real performance gains or mpg gains unless you delete the dpf. Check out thedieselplace.com for more suggestions.

    Gary, do it. You will never look back.
    My dually (02 crew cab 4 wheel drive) gets about 3 mpg better, up to 4 ish if I drive normal.
    So, about 12 to 13 with no programmer, and 17 to 18 with programmer. I get 14+ towing the boat loaded with support stuff.
    Duramaxforums has tons of info as does the dieselplace.com
    Stick with a reasonable tune, and you are good to go. Go max and your trans will hate you (andyour wallet)
    I have had the Banks, superchip maybe and not an edge evolution cts. I like the evolution. It has nice features. I run on level 3 of 4 and it shreds the tires.
    So, I'd recommend the evo. 4 levels. Maintenance manager. Allows code retrieval, etc. Some other cool and useless features.
    Good luck.

    What they said. Just DON'T use a tuner WITH your stock exhaust intact. MAYBE the Banks one, but that's mucho $. The reason being - ANY tune other than stock (and even stock) puts out some more soot - however slight. So, if you up the tune, you will REGEN (use extra fuel to burn the soot out of the DPF) more often. Like, all the time. I got the QuadZilla tuner, because you can switch tunes between WITH DPF and WITHOUT with the same box. There are others like it, but most are either WITH DPF or WITHOUT - but not both.

    The other nice thing about the Quad is, you can run the STOCK tune WITHOUT DPF. So, I can see how much the stock tune smokes - which is interesting, by the way. If you are pulling anything and start to pull a hill in 6th - it throws a bunch.....STOCK. I am up a solid 2mpg from stock exhaust. A guy on DieselPlace dyno'd his truck before and after stock exhaust / MBRP, but ran stock tune both times. 40hp and 40tq just to run the exhaust stock. If that wasn't clear - he gained 40hp and 40tq at the wheels by replacing stock exhaust and still running stock tune.

    BTW, 2008 C3500 dually (pictured below). MBRP turbo-back exh, Banks intake, QuadZilla tuner.

    I had an 08 (LMM engine) and used the Edge Evolution with the stock exhaust and really liked it. The biggest plus for me was I could run a really mild tune (30 HP) and see how often it was going to regen, when it was going to regen, and almost every engine paramater that the duramax tech's could see when they pluged in the tech2 programmer at the dealership. Now the "race" version with the CS or CTS (color screen or color touch screen) has the DPF delete option. I would mainly watch soot grams, EGT (probe in the exhaust manifold), Boost, and voltage at all times. Hope this helps.

    Where do normally keep yours tuned? I have ran the 50,70 and 90. I like the 70 the best so far. Been running this set up for 2-3 years now. Never tried the stock and economy tunes.


    I will add one more thing for the poster:

    If you do these mods, invest in a good set of Boost and EGT gauges on the a-pillar.

    I Normally run the 70 or 90. I have the TransGo Jr. Shift kit to go into the Allison to be able to run the 120 or 135, but don't really want to put the motor through that. The 90 is plenty crisp for me and I can handle the smoke output. Any more smoke than the 90 just turns me off.

    I haven't put in any other gauges. I only tow with the +50.

    The Econ tune doesn't get any better mileage than the 70 or 90, so I stick with those.

    Cool thanks. I called tech support at Quadzilla a couple months ago to see where people were getting the best mpg increases with the tuner. The guy said depending how I drive the 70-90 tune is best. I like the 90hp tune (I ran that for about 2 years with no issues), but I run 35" tires so I feel the 70hp is a lil safer tun for me. However I just serviced my trans again and had a fluid analysis done and everything looked fine. So maybe I will go back to the 90hp. I always tow on the 50hp. A few times I have been lazy and just left it on the 70hp and I could really notice the difference in EGTs.

    for an 09 dmax I would only look to a EFI Live solution. There are lots of great tunes out there, much more support and future expansion options. Esp if you think you might want to start upgrading other parts (turbo, injectors and the like)

    I rebuild transmission for a living . 99% of failed allisons have an aftermarket controller in the truck . my theroy is that because the trucks main computer uses adaptive learning ,peaple are changing the setting to much & not giving the computer a chance to "learn" . so guy turns it down for mileage, then cranks it up at a light or a hill to race some one or what ever ,than turns it back down again , and so on. the trucks adaptive learning setting are confused. just my opinion. however like i said for ever allison LCT 1000 I do ,I'll bet theres a controler.
