inTune i3 for GM Platinum is rated 4.2 out of 5 by 47.
Rated 3 out of 5 by from DiabloSport I3 Platinum GM Bought this about a month ago, and was excited when it came in. Purchased this I3 for a Silverado 1500 with a 5.3 and a 6 speed trans. Seems to be a decent tuner, but will throw System too Rich codes without the use of and aftermarket Cold Air Intake. However, I would not recommend using any of the Transmission tunes. After applying the firm shift tune, I noticed the shifting was considerably worse. Restored the backup to the TCM but that did not solve the issue. Luckily I had access to a GM Tech2 at my Chevrolet Store, and after re-flashing with the factory setting everything was back to normal. I now only use it to tune the ECM and read any codes that might come up.

Rated 4 out of 5 by from Easy to use. Easy to use. I used it to turn off AFM and Diablo Tune. I can really tell a positive change in power. Had tune for 4 months and reset to stock for a dealer visit. It worked great and was very easy. The only issues I have with it is a bug with disabling AFM. If you set "YES" to disable it does not. You have to set it to "NO" to disable AFM. And the engine pulsates very slight (25-50 rpm or so) on the highway. When I returned to stock for my dealer visit the engine pulsate stopped. It is noticeable but worth having AFM turned off. As of my last update 4/2018 the AFM bug is not addressed yet. When I reinstall the tune in July I will update I3 and see if the bugs have been fixed.

Rated 5 out of 5 by from platinum i3 and the "Diablo" tune this thing kicks butt. a was happy right away but now it has been a few days and 200 miles later. its doing better now than the day I installed it , the "Diablo tune". .....1st gear to 2nd gear would chirp or Bark the tires ( stock or no tune) first day of install it would fish tail 3-4 times when shifting from 1st to 2nd (big and noticeable difference ) that it has been 150 miles +(since Diablo tune was installed) when it shifts from 1st to 2nd it doesn't even slow down you can hear it shift but just continues to lay down a tire shredding burnout thru 2nd gear , wow!!! pretty peppy!!!! 2002 formula 95000 miles original stock. automatic.....….

Rated 3 out of 5 by from Capable tool, but lacks user options I bought this thinking I could make several adjustments to the engine and transmission control units. While the unit is capable of this, it requires the use of special software that only "dealers" have access to. For the money, I expected a little more end user control. This, however, seems to be the unfortunate trend in the vehicle tuning market. I was able to turn off the engines active fuel management (displacement on demand), which is worth every penny I spent on the unit so I have no regrets. Physically, it feels cheap and is much smaller than I anticipated. The display quality is sub-par. In the future, I will probably go with an open-source tuning platform. If you're not knowledgeable in the world of engine tuning or just need to make basic changes, this is probably the best way to go. Advanced users should look elsewhere.

Rated 5 out of 5 by from Noticeable Difference! I bought this to get a little better performance and for larger tires I have purchased for my 2015 Chevy Silverado Z71. Before putting the larger tires on I programmed my truck with just the 87 Octane performace mode, firm shifting, and speed limiter off and noticed a great difference right away! Better up-shifting and down-shifting through gears, better throttle response, and higher RPMs when I need it. I've been lighting up the tires that I'm about to get rid of! Will soon test the larger tire speedometer calibration!

Rated 4 out of 5 by from Good tuner. I received the i3 in perfect condition. No problems tuning my truck (2007 Silverado 1500 5.3L). Have tried several of the tunes and have tweaked the parameters to my liking. Main reason I purchased the inTune was to rid myself of the nuisance known as AFM, which was easy enough to do. My only complaint, so far, is that I won't scan my other truck's DTC's. The inTune is supposed to be able to scan any vehicle (even if it's not 'married' to said vehicle) but will not scan my 2004 Silverado 2500 HD 6.6L. It just sticks on the "Please Wait" screen.

Rated 5 out of 5 by from Amazing!! I was getting 22mpg with my 2016 Colorado 3.6V6 when I bought it. Not bad in the Oklahoma wind. Then I put a 6” lift and 33” tires on it and it went to 17mpg and power was pathetic. The main reason I got the i3 tuner was diagnostic and speedo calibration. Figured let’s go ahead and download the 87 octane tune with firm trans shift while reprogramming speedo. Only been 3 weeks and up to 20.7 mpg and runs better than did before lift. Throttle response is amazing. Power is back if not better. Larger tires always lug an engine but it runs so much better than stock with factory tires ever did. The firm trans shift is amazing. Factory trans program felt lazy and unresponsive never sure what gear it wanted. I loved my truck before lift and tires. Then I installed lift and tires and thought man did I screw up. This little Chevy ain’t happy now. Now that I’ve installed the tune I love my truck again and it begs to be driven hard. Excellent job Diablosport!

Rated 5 out of 5 by from Worth the Money What can I say? It does what it says it’ll do. Main reason for purchase was to shut off the AFM on my 5.3 Silverado. Figured I could just disable the AFM, or I could spend a few extra bucks for a full tuner, it was a no brainer. Easy to set up with the WiFi, I was plugged into my truck and playing with the tune within 20 minutes of having it out of the box. Diablo tune turned my 2016 Silverado into a racecar, I added an AEM CAI and set it to CAI tune, leaving the TCM alone. 23-25 mpg isn’t uncommon, and I’ve even gotten close to 30. Performance and handling wise, I have a new truck all over again. Every aspect of performance has improved, and no more searching for gears while under load. My Silverado is fun to drive now. Stay away from the throttle boost on a stock vehicle, you’re just going to run into issues. Make sure you’re running the proper octane fuel, and you’ll be completely satisfied with this product. Pictures were a 100 mile trip on mostly flat roads, pulling a trailer as pictured. I’m sold!

What that means is that we do not have any emissions compliance numbers for this product. We have 50 state emissions compliant products as well but for those who want custom tuning capability or higher power levels, we offer these products.

Wondering how I go about getting custom tunes for my 2011 Chevy 6.0 and my 2018 5.3 or find out how much the per loaded tunes can add for hp and mpg 

Asked by: Sawdog
You would want to contact a CMR custom tuner. I'd suggestion someone like Diablew Custom Tuning and he can discuss what kind of gains to expect.

will this tune support long tube headers with no cats?

Asked by: StrokerDriver
Our pre-loaded tuning with not be able to compensate for removing emissions equipment, unfortunately. Some custom tuners may be able to look into that option with you but our pre-loaded tunes do not help with emissions delete.
