Finally the response is still there. Soon a custom toon will be added for even more out of the ecotec 3 v8! Love the tuner.

Great product

Very user friendly device. I did see a 1.2mpg increase and felt a slight power increase also. I did the 93 octane tune. What I like best is I was able to turn off that AWFUL AFM GM uses on their trucks, now it's in V-8 mode all the time, no more of that dull sound out of the loud pipes when in v-4 or v-6 mode. I also increased the shift firmness, definitely chirpped tires a few times when I had to really get on it lol. Only wish the touch screen was more repsonsive.

Great Product!

Fixed all the shift points on my Sierra, I can feel the difference in acceleration and overall torque. Spend some time and really customize your truck. I changed the tire size, shifting, fuel type, and fuel injection slope. I can really notice a difference now.

Great Product

I have a 2010 dodge ram took it to the drag strip 1/4 mile. Before the tune my best time was a 15.1 On the diablo tune i ran a 14.6 I have been running the gas mile tune and receive about 1 and 1/2 mile per gallon more. I never calculated it how ever I can tell by how far I can go on a tank. I use to do about 280 now up to 300

Winner for EcoBoost

Very impressed with the ease of changing tunes and the actual difference each tune makes. I used the Tow mode while towing a 20 foot steel car trailer with a Mercedes E Class sedan on it, and it was excellent. I could easily get up to 70-75 mph and it was very effortless. I have been running the 91 Octane tune the rest of the time and my truck is a rocket, while getting a solid 18mpg even with lots of short trips. Bang for the buck is exceptional.
