Diablo 8200
Exactly how I thought it would be, easy to use, added good power with the 93 octane tune and trans shift firm tune. Transmission runs cooler, engine runs way better and feels and shifts right on point.

WOW
Installed this into a 2009 Silverado with a 5.3. I updated the unit first and set up the wifi before I went to the truck. I also registered the product automatically at that time. The next day after work sat in the drivers seat and plugged it in. I installed the 93 tune, firm tranny shifts and removed the speed limiter. The programmer backed up the original truck settings before it installed the new settings. The check engine lights went on and off, door locks went up and down and it stopped. The tuner said it's finished and enjoy the tune. I went back into the advance settings and under ECU I turned off the DOD, it reprogrammed it for that. Same procedure with the truck dash lights blinking then I get the your done message on the tuner. I unplugged the unit and fired up the truck. No idiot lights and the truck was running smooth. Took it for a spin. No issues. I stepped on it and my head bounced off the head rest. Holy Smoke this truck is alive now. It's faster than before. It put a smile on my face. It's worth the money. I'd recommend this to anyone.

Don't buy the used one get the new one
Do not buy the used one I did not know people are returning them after they tune their truck with it so it's married to another vehicle and you cannot use it I was really disappointed so now I'm waiting for the return so I can purchase it brand new and hopefully that goes through quickly because I'm excited to get the new one it's a great product I just should have known better than buying the used one trying to save a couple bucks

Pretty good product, made a bigger difference than I thought, just do your research
So I used this for drive ability and performance for my 2015 GMC Sierra 5.3. And to improve towing and delete that stupid DOD and AFM. It did both and I’m currently using a can tune for 87 octane. Makes a pretty big difference and drives much better than stock. The only things I can say thats negative.. 1) it froze on me in the middle of setting my tire size. Had to pull my negative battery cable off and then pull the module out and back in to reset it.. was worried about messing up the CPU. But it corrected quickly. I read online that you should pull the battery cable if this happens. And was able to reflash what was needed. It also saves stock parameters on the device. so if you need to go back to stock for service at your local dealer, you can. Also make sure you have immediate WiFi “AT ALL TIME“ during the tune and download ANY updates before you even start. 2) very vague on written instructions on how to do stuff. This the 4 star tech support rating. I here they actually are Johnny on the spot if your in a bind. But luckily I didn’t have to go that far into the rabbit hole. 3) Lastly, and it isn’t a negative, just good info, only use the octane tune you actually fuel with.. I can’t go full diablo 93 tune because no one in my area sells 93 octane.. and as soon as I get this 89 octane ran out of my tank , and fill up a couple times w 91.. I will switch to the 91 octane tune. If you run a higher tune with a lower octane, you will start pinging and run the risk of blowing stuff up in your motor from running too lean on your fuel trim. All of these that I’ve listed either I’ve already been through, or I had to do a lot of research online .. def do your research before attempting. Gas mileage I can’t tell yet. But the way I drive, I expect a decrease. Lol. I would have given it 5 stars because it does make a huge difference in just drivability, except it froze on me during flashing, and put me in panic mode.. and In the written directions it comes with, should describe what you should do if that happens so you don’t stroke out thinking you messed your ride up.

Issues at first
It was way out of date, so I couldn't connect to WiFi. Fortunately there's a program for PC's to use for updating the device. After I got everything updated it works flawlessly

Why didn't GM even come close to this?
This 2016 V6 Colorado was the most irritating vehicle I have EVER owned and that has been a lot of vehicles. The transmission/engine combination is a total mismatch so I thought. Regardless what the magazines say, my 2013 Hyundai Santa Fe Sport turbo 4 banger can tow a load more comfortably, better MPG, pull hills without downshifting and if you pushed the accelerator a little bit you went a little bit faster, if you pushed it a lot, you easily enter high speed traffic. The Colorado could do non of this. Even though I was going to take a huge depreciation hit, the Colorado had to go. My son talked me into trying the Diablo programmer since he was very happy with what it did for his 2015 V8 Sierra. This programmer has totally changed the truck!!! It is now a keeper. It's actually a joy to drive it now. You push the accelerator and now something good happens instead of actually slowing up on a hill. MPG is up about 1 MPG and considering that I'm continually "testing" it's performance, that is great. This wasn't cheap but it sure beat the big hit I would take getting rid of that slug.

Solid for my 2018 Silverado
I’m a nematode. But this was easy to use, feels strong and not cheap in quality, and I was able to do so much. Change the rev limiter, recalibrate the speedo for my 34’s, put a firm shift tune on, do a DOD delete, and put on a little MPG booster, super functional. I do wish the screen was a little brighter, I had to hold it like a foot away from my face lol.

Please Do Not Buy!!! Do your research!!!! I wish I would have!!!
-10 stars if that was a possibility. Please do your research before you buy. This thing completely screwed my truck up. Everything worked pre-tune. Now the only gauges that work are the oil pressure and voltage. My ac doesn’t work, and neither does my radio. I sent it back to Holley they reprogrammed my pcm and sent it back. It’s doing the same thing as it was before. I called them and of course it’s not their fault or the tuners fault, so just like a bunch of other people, im left holding the bag. DO NOT BUY!!!!!!!
