Superchips Questions and Updates
A little more teaser... Three things I've been toying with.
First: Eliminate shifting into 2P. In theory if I set both 3dn and 2Pdn shifts points' curves to overlay exactly (TP% same from 0% through 100%) when it attempts to shift into 2P, either at light throttle (07 & up) or 75% throttle (all years) it will drop into second as opposed to 2P. So far, my theory works very well but you have to ask is dropping from 5-2 better than 5-2P? After all the RPMs jump from 1700 to 4500 when shifting from 5 - 2 at 65MPH. One benefit though is I no longer have the whine that shifting into 2P caused and I have better pulling power passing in second as opposed to 2P. I'm testing all three shift schedules with this theory.
Second: I've been playing with setting the "default" Shift Schedule to a "modified stock" Shift Schedule to give me a little better mileage with day-to-day driving. Then setting the OD Off Shift Schedule to be more aggressive. If I want to put my foot into it, I'll hit OD Off to have a bit more ****&vinegar and, I really don't care about 5th gear when I put my foot in it. Now I can have my Kate and Edith too. Also the OD Off Shift Schedule has better low-end pulling power that is helpful when hauling.
Third: The Low Shift Schedule's TP% and MPH ratios are much better correlated for 4-low now. I don't do a lot of off-roading or hill climbing but I can see where this will be extremely helpful for the off-road enthusiast.
We're still working out a couple of issues and it's taking time to work through them but, as you can see there are a lot of options that will be available to you.

Econo tunes are usually the worst. Ive never gotten better from the econo tune but usually the opposite. 87/91 tunes are better as far as pep goes but again, it was more power if you will but never any increase in MPGs for me. No matter anything I have done (and ive done alot) Ive never seen any increase in MPGs.
Bottom line, dont buy a SC for mileage. Buy one if you want a bit more power out of your ride and more control over your truck functions.

Yes, I believe you can. The Hemi engine runs much more efficient if you can keep it in the power band (NOT WOT). What I mean is when you have to use a lot of throttle to "poke along" as you do with some of the mileage tunes, I believe you're using more fuel less efficiently. With a 91 tune you don't have to apply near as much throttle which may save fuel in the long run. Make sense?
i have a 2003 with the 5.9 im looking into getting the supchips for my truck just wondering if it is really worth it for the 5.9 motor? I have herd yes and no.... Also i see they offer 2 a 3815 and 3865 the 65 being more expensive whats the difference?
any help would be greatly appreciated thanks all!!!!
