Thought I would start my review of the EcoDieselUSA Stage 2 delete tune I purchased. I currently have a little over 300 miles on this tune. At present just the engine is tuned, I haven't received all the devices needed to tune the transmission yet. In one word, WOW! Really woke the truck up. Smoke is very, very minimal and the sound is just right. I purchased the 3" exhaust pipe from him also. They are still working on the pipe design to connect at the point before the split in the rear. The one I got, I had to cut the exhaust right behind the last sensor with the flap in it and connect to the exhaust there. Will be better connecting at the junction. Beware of using any other pipe unless you know for sure it connects in the front at the junction where the DPF connects. His tune uses the smoke sensors just upstream from that point.
I used an app on my cell phone for before and after 0-60 times. The app is notoriously high but it is consistent. I hope to get a Dragy for Christmas and get some accurate times later.
Before with stock, the truck would barely chirp the tires and ran 0-20 in 1.8 seconds, 0-60 in 8.817 seconds, 0-100 in 24.79 seconds, and 1/4 mile in 16.83 @86.21 mph.
After the engine tune the truck really spun the tires too much. I realized when I got back and looked at the results, I needed to take off in Auto 4-wheel drive mode. 0-20 in 2.801 seconds, 0-60 in 8.813 seconds, 0-100 in 19.841 seconds, and 1/4 mile in 16.821 @ 93.71 mph. As you see, I lost time at the startup due to wheel spin. But still got to 100 mph 5 seconds quicker even with the tire spin. Miles per gallon so far is about 2 mpg better than stock. I ran the truck up to 132 mph but it still had more to go! I'm guessing, but think 135-140 is where it will land topped out. I will update with more info after the transmission tune and I get some miles on. I really cannot compare it to any other tune because this is the only one I have experience with, but needless to say, I am very, very happy with this tune.
