From the southern tip of Illinios, Cairo to Chicago, 360 miles I would run a mild setting with cruise set on 65. So I futher conclude that Mini-max focuses on 1st getting the most efficent burn from a drop of diesel then maybe it will raise the fuel rail preasure for more power or in hotter settings. I do remember reading that cummins stock injection events are focused on pleasing the EPA and sacraficing economy to do this. I conclude from this that I am using the same amount of power in both settings, but the mild setting is producing a more efficient burn of the fuel, not by raising the fuel rail preasure but it is perhaps doing this by injection timing, injection pulse, width ,and duration or even perhaps number of pulses per event. (perhaps it would be if I was pulling a hill). This was very exciting for me as I thought the fuel rail preasure would be the one raising. The fuel rail preasure and boost remaned the same, only the pyrometer tempature went up 50 degrees and would drop 50 degrees as I switched settings. Then I observed the engine guages and what they read when I did this. I also tried hot and wildest settings but they gave me the same results as mild so I decided mild would do. Wow it was like magic, each time I watched the bar graph rise and then fall as I switched settings. I said, " No way, I don't believe this!" So I did this numerious times to verify to myself what I saw, allowing a minute each time. So on the fly I bumped the mini max to a mild setting, I watch the bar graph rise to 18+, I reset it and yes there it is at 18. So I'm coming home Yesterday in Missouri on I-55 and the road is just flat-flat, no wind, no pulling a load, and I thought this would be the perfect time to see if a mild setting might make a difference on fuel economy. Yesterday, I had an awaking moment, a change of thinking. At the same time I am left wondering why my 2011 6. That is by using the Mini max on stock settings and that is what I intended to do. In the most recent issue of TDR I read a study by Robert Patton that I had only gained maybe. Had to drop the crossmember to get the down pipe out but H&S provided excelent instructions for the whole procedure. The EGR cooler has some very well hidden bolts that I finally found and had to remove the cooler 1st to get a wrench on another 15mm bolt at the front that was inaccessable. I also installed an exhaust probe pre-turbo. Then I went the ultiment step and removed all the EGR and DPF using the mini max to erase the 6-8 codes that poped up. Just over 2 weeks ago I did the unthinkable, I installed a mini max for a day and drove around town just to get used to it. I remember the 60s and 70s, there was smog and polluted air and the EPA did a good job on reducing this as now we don't have that, but In my opinion they have now gone off the deep end into extreme measure. They want to force me to pump dirty soot exhaust into my clean air engine intake and use 4$ diesel to burn off the soot in a short life costly particulate filter. I know the 3 things an engine needs, clean air, clean fuel, clean oil. " Now the EPA has completly changed the ball game and is pushing me to eat my words. I had always said, "I will never put a chip on a truck because it always asks the injectors and various other engine components to do something they weren't designed to do, causing premature failures. The 2nd one I still have and am going to sell it soon. The 1st one I got 930,000 miles out of it. The previous 8 years I have used 2003 trucks. My main goals are off course to make a living, so fuel economy and engine/truck longivity are my main concerns.
