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.

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.

The media could not be loaded. -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!!!!!!!

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.

If you're on the fence about this product just do it! I have a 2004 dodge ram 1500 5.7 hemi. Before loading the Diablo 91 octane tune my truck had slow sloppy shifting and throttle response was so slow. At cruising speed I had to nearly floor the pedal to get it to down shift and it just felt bogged down. Now with the Diablo tune the response is instant!! It's almost scary. My truck has alway had good traction on dry and even wet roads but now it will light the tires up on both. I've had to change the way I drive to keep her planted. I will say that the improvement was not immediate. It was probably the 3rd day after loading the tune when everything clicked with the tune. The most beneficial adjustment was the throttle response adjustment option. It gives you the option to adjust response 1% to 20%. Do the 20%! It will make you fall in love with your hemi all over again! Go lightem up!! (Update) Can't express enough how important it is to make sure your engine is running cool (180 thermostat) after loading the tune my truck was running waaaay better especially in the mid to high RPM range. But I noticed my motor was still running around 200 degrees even with the 180 thermostat (bought from local auto parts store) so I ordered a Mishimotto 180 thermostat and installed it today. Mercy it was like adding a tune to a tune. Now I'm truly running in the 180's. The power is across the board now and just light the tires up dangerous. Before loading the tune make sure you have all other mods complete first. The power of the tune is dependent on other mods like thermostat, CAI, exhaust.

Purchased this to disable the AFM in my 2007 Chevy Suburban and it worked perfectly. The tuner only took about 15-20 minutes to backup factory tune, install new tune and disable AFM. Would highly recommend this for anyone with a 07-13 Chevy Suburban if they want to do the same.

So glad I purchased this. I am able to tune my truck when ever I need. Needed this when my truck rejected the throttle controller that I put on. Tuned the truck, adjusted the throttle, and removed the speed limiter
