Review on Unleash Your Vehicle's Potential with the 8200 DiabloSport inTune i3 by Rodney Mendoza

So I used it to improve the handling and performance of my 2015 GMC Sierra 5.3. And improve towing and remove those stupid DODs and ACMs. It did both and I am currently using a can set to 87 octane. Makes quite a difference and handles much better than the stock. The only thing I can say is negative. 1) it froze in the middle of setting the tire size for me. Had to disconnect the battery negative cable and then unplug and re-insert the module to reset it. worried about the mess of the processor. But this was quickly corrected. I read online that you should unplug the battery cable in this case. And I was able to reflash what was needed. It also saves inventory settings on the device. So if you need to return to your local dealer for service, you can. Also, make sure you have instant WiFi "ALL THE TIME" during setup and download ALL updates before you even begin. 2) very vague written instructions on how to do something. This is a 4 star technical support rating. I'm here, they're actually Johnny there when you're in a tight spot. Luckily I didn't have to go that far down the rabbit hole. 3) Finally, and this isn't a negative, just useful info, only use the octane rating you actually fuel with. I can't get past the full Diablo 93 tune because no one in my area sells 93 octane gas octane number 91. If you drive a higher octane tune with a lower octane you will start honking and risk banging something into your engine blow because you are too lean when trimming the fuel. Everything I've listed I've either been through or had to do a lot of research on the internet. Definitely do your research before trying. Can't say fuel consumption yet. But I expect a decline in my driving style. Rschunimagu. I would give it 5 stars because it only makes a huge difference in handling other than it hung me on flashing and put me in panic mode. and The written instructions provided should describe what you should do if this happens so you don't think you've ruined your trip.
