31-33 mpg for most driving, 18 mpg towing my 6500 lbs farm tractor. I should note that I have a tune, and I don't think I have ever driven faster than 60 mph in the past year.
It could be the same, I just don't know. I've taken mine back to "stock" too, just to see how it works. It is easy too, but I was told by HD Diesel that "stock" isn't really "stock", but some resemblance of a stock tune. I'm just worried that if the dealer reflashes and it doesn't match, the...
Many??? Which many??? The HD Diesel supply tune with the handheld device has only been on the market for 8 weeks (I was one of the very first to purchase)...point me to someone that's done it.
Any of you guys with the HD Diesel Supply hand held device tune take your truck in to a dealer yet? I know HD Diesel say you can tune it back to stock, take the truck to a dealer, then tune it back after the dealer, but I haven't heard of anyone doing this yet, and I'm not ready to be the first...
Yes, I had the AEM. But, I have a take home car to drive back and forth to work and my truck is for weekends/pleasure, as well as where I live I drive 5 miles of dirt road slowly before I hit pavement. My truck is always warm when I stomp on it, so I've never really noticed lag.
I drove mine with the new tune, but couldn't feel a difference in power what so ever. MPG is drastically improved...so drastically, I'm not sure I'm believing it.
The tuner seems to have re-flashed my truck, although its not appearing any different yet (and HDDS said I would have CEL for the first five starts, but I have no code). I haven't made a test run yet due to the area coronavirus shut down
After two days I still haven't heard from HDDS (coronavirus? IDK), but I seemed to have found the problem was from using the SS type USB ports of my computer. The normal USB ports are hard to get to on my desktop, but when I plugged the programmer in there, it now seems to have gotten past the...
So mine arrived, and its the Alientech Powegate programmer. Problem is, it doesn't work. I've been dealing with it for 2 days now. I'm about to send it back. BTW, I know computers, and I even already use an Alientech Powergate on my Hemi C. I'd stay away from this one.
