🔥 DiabloSport 8245 Performance Programmer Gen Review

Like DiabloSport, it is smaller than the old version but has more features. My only minor gripe is that it updates EVERY time you plug it into your home computer - not daily, but easily a couple of times a week. It's okay that they update the software, but unless it's a critical update, you might think that they compile updates and release them every two weeks, for example. Otherwise it would be 5 stars in line.

I didn't know what I was getting into as tuners had heard good things about it so I gave it a try. My 2012 GMC Sierra 5.3L vortec WT Single Cab Short Cab pickup had an octane rating of 87. They also tuned the hardshift transmission and got the right tire size. In terms of fuel economy, I went from 15 to 16 with moderate driving. There was a noticeable difference in performance for me, but I think it's mostly the feel you get from the shift tune. In general, I've had it on my car for a little…

I only bought 3 only 1 worked. The tech department said they never had the same problem I had with the 1st but they were happy to send me a replacement asap. This replacement worked. I bought another one (3rd) and it keeps asking for updates. Even the ignition program you use to update the programmer says it updates every time. Unfortunately when connecting to a car (2018 Silverado) it says an update is required. Enough aggravation. On the plus side, the programmer that worked worked, although…

This programmer is cool I didn't buy it to increase fuel economy I don't give a damn about fuel economy. I installed it on a 2015 GMC Sierra SLT 6.2L 8 speed. I selected the Diablo tune, turned off AFM/DOD, disabled the speed limiter and set the shift points to hard. I immediately noticed a difference in performance and handling. And the most amazing thing is that my average fuel economy is already up 6mpg and I've only driven it a hundred miles and it's still going up. And I drove harder than…

plug in and follow all the instructions as it will update automatically. By default, an update is required before installing in the car. (edit follows) So I've been using this tuner for over two years now and I still ABSOLUTELY love everything about it and what it does for my 2018 Silverado LT truck with a 5.3 L83 double cab 6 speed auto transmission and 3.42 2WD axis does . I bought this 8245 long before 8246 was available and now I see that 8245 requires an additional fee to unlock 2017-2019.

I have used many tuners in the past and they were very easy to use. I have 40 years experience as a computer engineer so based on the reviews I expected this to be easy. An update was not possible via WLAN or a computer. Wasted 5 hours and ended up leaving it overnight (as some have suggested). Woke up to refresh. I bought a second license with no problems. Did a basic setup on a standard Hummer H2. It turned out that the performance and handling improved during two short test rides. On the…

So before I go into details, please understand that there are other tuners that could be better, but I haven't seen it worth the extra money considering I'm using my Silverado 2015 and THAT I'm not smart when it comes to ECM changes. My main concern was changing some parameters, getting some mpg, and if I add some aftermarket mods (CIA, exhaust, etc) I can also talk to a custom tuner for an extra $$$ to tune the AFR reduce. From what has been said I think this tuner is worth the money. I've…

I was looking for a tuner for my 2018 Silverado that went a little further than canned. At 355.00 it looked pretty good so I went for it. I was very excited when it arrived and read that it needed an update before installing it. No problem. The device was practically Wi-Fi and was only powered by my laptop. Did! I even ran it again just to make sure it was up to date. Went to my truck ready to install. Well you see the message I received. Angry, I went back and updated again. nope I contacted…
