It was just the thing I needed for my Ram 1500 5.7

    • Does not work as described
I purchased this for my lifted 04 Dodge ram w/5.7 Hemi for the sole purpose of calibrating my tire size. Spent a total of 5.4 hours on the phone with Amazon tech and Diablo/Holly tech to fix the issue and wasn’t able to. Diablo tech said it was not communicating with my vehicle due to certain sensors Dodge said they worked fine I replace them anyways and the programmer still did not perform as it claimed. Ultimately sent it back. Will purchase a different brand in the future if Amazon ever refunds my money as they claimed they would before I returned the item to them. Beware a lot of frustration and negatives with this purchase for me. ... show more

    • It works
I was able to turn my MSD off and raise the speed limiter on my 13 durango citadel 5.7 , put the tune in it and woke it up big time. Can't wait til spring to turn off the awd and shred some tread

    • Good HP gains for the money
Purchased this for my 2014 Ram 1500 5.7l with an 8speed transmission. I was very very skeptical about this tuner sense the reviews were hit and miss with the tech support, transmission tune, and ECU lock up. I took a gamble on it and purchased it. Once I received it, I immediately updated the software to the latest one available. Once the tuner was updated I took a huge breath and plugged it in to the truck. The tuner goes through some typical questions and then Once you select the tune you want you can program your vehicle. It makes a copy of the trucks original tune and stores it for future reset if wanted. It took about 15 minutes to program the tune and everything went well. I took the truck for a ride and I was immediately shocked on the difference in performance. Yes I lost a mile or so in mpg but I was not worried about that. Now one of the main questions on these 2014 Rams with the 8 speed transmissions, it didn't effect the transmission at all and also shifts at much better rpm's. I also must mention I do have a full exhaust system upgrade and cold air intake. I had these upgrades before the tune. I would still be skeptical on this tuner just for the fact that there is so many questions out there about different problems it may cause. I took a gamble and tried it. My outcome was good and the power gain is definitely there. I would recommend if you do purchase this tuner, update it immediately after receiving it and before you tune your vehicle. ... show more

    • Fast and easy set up.
Honestly I thought it was a gimmick but was told to give it a shot for my 2005 chrysler 300c 5.7l hemi. Got it out of the box and updated the device wirelessly which is sweet. Went out to my vehicle and plugged it in. Canned 93 tune woke this car up something good. Now I'm not saying this made my car a race car but for 400 bucks this is a steal for just the instant throttle response and how new the car feels. If you're on the fence because of some of the bad reviews on here, don't be swayed by that. Try it yourself and make sure you get the model that fits your VIN and you'll have no problems other than wanting to drive more. ... show more

This had a VIN already attached. It would not work at all for tuning. Reading codes yes.

    • Should give you more options to tune
I liked the easy set up, what I didn’t like was the fact it doesn’t let you tune you’re car to your liking, you can only choose the pre tunes that it comes with
