    Rated 5 out of 5 by from 2017 Silverado 5.3 wake up I was really not happy with the performance of my Chevy. I drive 60 miles a day too work and back. Country roads and I-10 traffic.I was at the point were I was considered buying a Ford150. I know I know. I installed the Diablo around 3 weeks ago. MAN I tell you WOW this thing really woke up. It was really easy to install. Just make sure that it is updated first. If you plan on installing over the weekend. When you get it in take the time to hook it up to your PC for updates. Super easy!!!! Now with this installed I’m getting better performance and gas mileage then I was in my 05. With the tune I’m still averaging 18 mpg before it was 19 -20mpg a small loss that I can live with. And that’s with canceling the AFM cylinder drop. Now I have a V-8 again. I did the 93 tune on mine. It does however come with multiple tunes on it to suit different needs. Check it out on you tube. I highly recommend getting this product.

    Rated 5 out of 5 by from Woke up the my Z Definitely has a little more low end torque especially with npp in closed position. No more 4 cylinder mode which caused motor and transmission issues eventually. One Disappointment is it had no tranny shift option where I read that it did.

    Rated 3 out of 5 by from Tuning made easy I bought this tuner a month ago and it was not working out of the box. I downloaded the update before use, and it needed some kind of vehicle unlock installed. I was able to get it right the next day, it sucks that tech support doesn’t have evening hours, I had to wait until the next day after they opened, so I took off work to get it done. but, I’m very pleased with the tuner now. Very easy to use

    Rated 4 out of 5 by from Happy So Far I bought this about a month ago, and so far I'm happy with it. It's not perfect, but it works as advertised. A few complaints I have is how cheaply made the device seems and the instructions provided seem a little lacking. Upon initially tuning my truck I kept receiving a message such as "the ECM on the vehicle has detected updates are needed before tuning", but I had already checked for and uploaded current updates prior to tuning. I finally figured out after about 30 minutes of messing with it that I needed to move my truck closer to my router to receive a better connection over my WiFi, and all of sudden I had it tuned within a couple of minutes. Other than what I mentioned above, I'm am very pleased with how my truck runs with AFM/DoD disabled(still gets 18-20 MPG) and the throttle boost set to 10% on the 87 octane tune and stock TCM tune. I bought the platinum for the custom tuning capability and plan in the near future to have Diablew send me a custom tune after I do some data logging. Lastly I'd like to add that the price doesn't seem too bad when you think of what all it does. It has the capability of a code reader, a Pedal Commander, a standalone AFM/DoD disabler. Plus it has pre-loaded tunes, custom tuning capability, data logging, tire/gear editing, and the capability of tuning other supported makes/models of vehicles for a licensing fee.

    Rated 4 out of 5 by from Great little tuner I've only had it a few weeks but so far I like it. Only made a few adjustments. I used the 93 octane tune, disabled the Advance fuel management, turned up the throttle sensitivity to 10. I was disappointed that I couldn't adjust transmission shift points and firmness.

    Rated 5 out of 5 by from Great tuner A Must Have for your 18 silverado I just received this Saturday. and wow what a difference this product has made in my 2018 Silverado 1500 4WD with dual 3 Inch exhaust conversion an Quad cab truck, first I tried the 87 octane tune and Immediately felt a difference in the power of my truck , so yesterday I tried the 91 octane tune, AFM off, Speed limiter off, Hard shift on trans, 25 percent throttle adjust Wow is all I can say!! this really woke up my already quick truck. Now when I step on it you can really hear the throttle body open up and my truck just roars, Had some jerk in a F250 yesterday trying to get a race out of me So I stepped on it in seconds he was eating my dust! If you are looking for a new tuner for your Silverado look no further this is the one to buy

    can you activate E85 tune? on 2018 Camaro SS

    Asked by: OBI1
    If the vehicle is a Flex configuration from the factory, the preloaded tunes will work as-is. If it came originally as gasoline only it can be tuned for E85 with a custom calibrated file from one of our CMR Dealers that have our software to do so.

    We don't have a definitive timeline on that support as those computers are more difficult to tune as compared to the 5.3L equipped models that we just announced support for. Stay tuned for more updates.

    Can I use my buddy's INTUNE 3 on my truck?

    Asked by: CS1731
    As long as both of you are using the same make of vehicles IE: GM/GMC or Ford....etc....Keep in mind that if you ever want to return your truck back to stock before you take it to the dealer then you will need to get it from him. BTW I always suggest restoring to stock before you take it to the dealer not because the dealer may see the tune but because they will most like write over it wiping out your tune. By doing so you will also reduce the chance of the license not working on your truck if they update the ECM and for some reason the Diablo i3 does not recognize your ECM.

    On my 2019 corvette I had to purchase the ECM unlock tune , can the dealership detect that if I return to stock

    Asked by: Suprnot
    The real answer is sorta. The dealer cannot see what parameters that you had changed whether you left the tune on or restored back to stock. Unless you get a tech who has the time to go thru settings and knows them well enough to know it is not stock. So the answer to that is not likely. What they can see is how many times the ECM is programmed. So each time you apply the tune or restore the tune the ECM keeps running tabs. Again unless they are paying attention and want to try to bust you or give you a hard time they probably won't notice.
