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.

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.

-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!!!!!!!

It works! 2003 Silverado. I am running the 87 octane Standard Tune. I have modified exhaust and intake. When I first got to give it some throttle after following the instructions exactly it really put a smile on my face when it shifted right away and climbed in speed. 👍

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.

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.

Update: Now it is frozen with the message "please wait for the tool to reboot!" and nothing gets it unstuck. It is unfortunate that a good performance tune is ruined by awful software running the user interface of this device. Original review: This is one of the few 50 state legal tunes I can use for my 2001 GMC Yukon Denali since I live in Commifornia. The 87 Octane tune seems pretty good so far. However prior to updating with the latest firmware, it is the worst performing user interface I have ever used. It would take several minutes to navigate through some of the menus, just so I could get it to update. Once the updates were applied via WiFi it worked enough that I could flash the tune onto the vehicle but still kept freezing up. After the unit freezes up, it wants to reboot before you can do anything with it, and this process takes forever (it seems to freeze during reboot). In my opinion Diablo should recall all of these devices until they fix the reliability of the user interface/processor. The device is absolute trash which takes away from what is otherwise a great performance tune.
