Happy holidays to all !!

Here's hoping '21 will be better !

Sorry for another mpg question and I'm sure this has probably been discussed to death somewhere??

  So I've owned my truck for almost a year now, I don't drive it much, mainly bought it for hauling camper, dirt bike and such, I don't think I've put more than 6 - 7 tanks of fuel thru it, maybe 3 since I got quadzilla.

 Was I mistaken thinking I was going to get better milage with the quad?

 I love the way it runs, and I drive pretty conservitaly most the time and I have yet to get over 12 mpg ! That was before and after quad, no difference other than power, which is nice but??

 Now I'm still extremely new to the diesel world and all these charts and graphs of timing, fuel curves, volumetric tables, etc.. just seem to make me more confused 🤔😵

 I'm really wondering if I should have just got the edge comp and been done? I was reading somewhere moparman was getting an additional 7 - 8 more mpgs with just the comp box. Oh well, too late now.

  When I'm not towing I'm usually driving mostly city and running the"daily driver with meat" level 3, I really like the tune, but does anyone have a good economy tune/tunes like one for city, low speed driving, and one for hwy with stock to 75 hp injectors? Time to save for bigger ones? Should I be driving with a higher or lower level?

 I kinda remember doing a idleing load test right after I got the quad to test injectors and everything was fine, assuming that test actually works?

 Or just maybe some advice/opinions on what's happening here? Or some easy to understand settings with small words in bold type, LOL!

      Thanks!

LorenS, thanks for taking time to clarify!

Glad to hear it wasn't just me 😂

So, do you just leave it at 40% now  for all driving conditions or do you or should one change it if you're going to be changing from 70 to 80 for a while , or you're going to be driving slow city stop and go for a few days?  That's how it is here where I live.

Have one tune for cruising 70, one for 80, city, etc ??

 

I think it's hard to understand how compeatly confusing this stuff is for someone that's new to the diesel world, (myself) hence why I joined the forum.

Even in the "gas world" I know my way around most aspects of a vehicle but I am no gear head/engine mechanic or tuner, were one plays with and really understands timing, and how it affects mileage/power. My specialty is auto body/ collision repair.

 

  Still need to get out and do this, like I said not my daily driver, (partially because of mediocre mileage) but should have enough info now to get this done!

 

 Thanks again to all for help and patience!

I don't believe changing it should be necessary.  If you set that Low Load Timing just a couple of percent above your normal, flat ground cruising Engine Load at say 65-70 MPH, then you know the engine isn't straining and can handle a little 'stress' of advanced timing.  If you're going 80, or 65 up a grade, or towing a trailer, then the engine load will be higher and the Quad will not allow the higher timing, thus saving your engine/head/etc.  With your bigger injectors, you likely won't have a cruising engine load as high as mine.

 

It is recommended to have different tunes for different things, like Towing versus Sportscar or Economy; towing you will likely have long duration of heavy load, and also will want to get moving even at the cost of a little fuel economy.

I'm no expert at any of this, either, so if I said something wrong hopefully one of the more knowledgeable guys will chime in.
