    Rated 2 out of 5 by from Idle Increase Bug - 6-Speed JK Quick heads up for anyone purchasing this unit with intent to increase their idle on a 6-speed will not work. The increased idle feature does not hold the selected setting and continuously returns to factory when coming to a stop (street and trail). After going through several custom tune files, we were unable to fix the bug. Unit returned.

    Rated 1 out of 5 by from Worst service I’ve ever had They send me the wrong part now I’ve been waiting 3 weeks for a return slip. I call and call and call nobody picks up, I’ve written 30+ emails with very little response. Never order from these people. Bad service. Hopefully they’ll read this and send it.

    Rated 5 out of 5 by from Great tuner I bought this thing to recalibrate the speedo on my Grand Cherokee after I did a lift and tires. I put in the mid grade tune and adjusted for the tires, and this thing WOKE UP! Idles better, accelerates better, and gets better gas milage (when I keep my foot out of it). Customer service is awesome if you can get passed the long hold times, but fixed the problem I had without issue or delay.

    Rated 5 out of 5 by from Excellent features Definitely a great buy. You can feel a difference in power, torque, and shifting points. Been driving on 87 tune for almost a month while fueling with 89. I don't have an issue with fuel consumption since I have 5.7 WK. I plan on trying 91 tune and give an update when I do so. Overall this is a great tuner for your average daily.

    Rated 3 out of 5 by from Update to prior review After many attempts. I did get it to update and work. The customer service representative walked me through the issue of no memory. The unit still does not so wifi it freezes everytime. I noticed some difference in 91 tune but no. Matter what time my gas mpg Is like 13 even on the higher mpg tune. But it does work now.

    Rated 5 out of 5 by from Great extra features Excellent product. Easy to use. Great tech support. Lots of expandable and extra features. Daily updates. I can also make fine adjustments on things like shift points, fan settings etc. Also purchased an extra licence to tune my other vehicle with the same tool.

    Rated 5 out of 5 by from Disabled MDS I bought this to disable MDS. I was nervous messing with my pcm. I updated it on the pc plugged it in to my obd2 port then it needed a wifi update to capture my Vin info. then I modified the stock tune and good to go!

    I have a i3 already that I used on another vehicle. Can I get a MDS delete program loaded to this unit. I don't care about anything else. Just the MDS delete. It's a 2007 Jeep commander 5.7 hemi. Or will I have to purchase another programmer?

    Hey, where do I find how to navigate the air/fuel and the timing advance settings in the program er.

    Asked by: MrIrish
    The options you may have will vary based on your application. However, you should be able to find any and all custom tune options in the advanced tune menu when you go to program the vehicle.

    I have a 08 srt8 grand Cherokee. It has aftermarket injectors, throttle body spacer . Can I use this or do I need the tuner with custom tunes?

    Asked by: Dane
    In this case, it's best to look into the intune i3 Platinum so you can upload custom tunes from a diablo CMR dealer. For the best price available, give us a call at the number below. 866-404-6141 DIAL 5
