I've never ran a Hyperpac, but I did run the Hypertech Max Energy for a while. I think their tuning is the same. For my money I prefer the Diablosport Predator or the Edge Evolution. Just my .02.
I have run the Predator and the Edge EVO. You can't go wrong with either one IMHO. I got an average of 18.6 mpg on the hiway (7 trips) @ 72 mph with the EVO on level 2. The Predator on levels 2 & 3 gave me an average of 18.2 mpg @ 72 mph on the hiway (5 trips). The Predator makes its power...
All-on
I just did the mod, except I ran everything off of the 85 pin of the low beams. That way the fog lights are on with the high beams and the low beams. Very easy to do.
I know this topic of increasing fuel mileage has been beat to death but I thought it would be interesting to know what others have done that they can HONESTLY say has increased their fuel economy.
Here is what I have done:
Predator programmer: maybe a small increase (1 mpg) maybe
4"...
I talked with Steve Shelley (the programmer) and he wants another shot at increasing my mileage. I said go ahead. What have I got to lose?
"Let us know how everything works out. Cowdoc, have you considered EFI live and a good tune to compare for MPG's against your stock numbers? Reason...
The verdict is in
Well, I have put 2100 miles on the Duramileage ecm. During that time I have averaged 18.6 mpg. With stock and/or Predator 65/85 hp tuning under the same driving conditions I averaged 18.1 mpg. So ther is an improvement, but it is a far cry from a 20% increase. I am very...
Well, I got 19.0 mpg on my trip out to Oklahoma. It was pretty windy all day and I drove through hard rain for the last 2 hours of the trip. That is a little better than I have gotten under conditions (18.0 mpg with stock tuning) in the past but a far cry from a 20% increase. The truck runs...
First impressions
I filled the truck up with fuel this morning and I have only driven the truck a little over 100 miles with the Duramilage installed so I can't say a whole lot about it yet.
Looking at the odometer and the fuel gauge, I am getting better fuel mileage than before, but it...
I just installed my Duramileage custom tuned ECM and took it for a short test drive. It is pretty impressive for 65hp/100tq (better than the 65 hp Predator tune that I have been running). Now we will just have to see if the mpg gains are in there some where.
I have done a ood bit of reading on other forums since I ordered the Duramileage and it is being called "snake oil" and a hoax. The od thing is that no one seems to have tried it. Other companies and individual custom tuners are marketing similar products and getting rave reviews, but most...
I wonder if this is the same thing: Diesel Performance Products, Parts, and Upgrades for your, GM Duramax Diesel, Pickup Truck - Aftermarket Diesel Truck Products
If it is I paid too much for the one I ordered. This is about $100 cheaper, but I don't know if teh guarantee is as good. Either...
