    i3 + PCM Swap, Dodge Truck 2015+ (5.7 8Speed) is rated 4.5 out of 5 by 2.
    Rated 5 out of 5 by from Very Simple & Good Results So I am very Green when it comes to knowledge of this area(engine, tunning, etc) yet I run around with a few guys that have some knowledge and different things done to their trucks. Naturally being around it and seeing what gains they received I had to as well. Each guy told me to review stuff and their opinions but always said go with my choice. Called around to mechanics n places that specialize in tunning etc and 3 out of 3 said a diablo programmer for the Ram is best they have seen. Fast forward...easy to purchase with easy instructions on exactly what I would need for my truck. Recieved Programmer n PCM next day. Back up in running in less than an hour with instant results. Would of been maybe 35 mins to 40 but i had to update device. Which was simple. Did Easy Tune first for 3 tanks of fuel then started with the Advanced Tune. Still adjusting things to play and test results with out changing to many variables. Each time I can notice some changes in what I am asking of it but mainly I can tell a big difference. The fuel economy side of it i havent gotten a true number on the gain due to not staying consistent but i have better fuel range when on certain programs of course. I would recommend this to anyone with a Ram or vehicle period after reading up on the items they carry and range of vehicles they cover. Costumer service walked me thru a simple issue and has been helpful everytime. I asked goofy questions but they seem to answer like they get it. So overall I give it all the stars n more but there are only 5. So I say thanks again for making the products you do and assisting with any issues. Now it's time to fly....roads, where we are going we dont need roads my friend!!! Buckle up !!

    Rated 4 out of 5 by from As expected Purchased this set-up mainly to correct the tire size on my Ram, but also uploaded the 91 octane fuel tune and increased the throttle response by 5%. Now my speedometer is accurate and the transmission shifts at the correct time also the throttle is very responsive and the power from the tune is very noticable to me. 2015 dodge Ram 6in lift and 35in tires.

    I have va 2018 5.7 with the pulsar, would your product give me more horse power along with trans shifts and speed control

    Asked by: Chris T
    Yes, the tuning would give you more options in those areas but you would have to do the PCM unlock process in order to tune. You won't have custom tuning on all those features but you will see improvements across the board with tuning.

    Is this compatible with a 2014 charger v6

    Asked by: Pulido55
    No, you would need the regular 8345 to tune that vehicle. The product you selected is for a 2015 and newer V8.

    my 2019 1500 5.7 rebel is governed at 103. Just cuts out. Will this change that?

    Asked by: Josh59
    You would want a different product altogether as the product you selected doesn't support your vehicle. This product will remove the speed limiter. 93 Octane Performance Tune: 33HP 28TQ 91 Octane Performance Tune: 26HP 22TQ 87 Octane Performance Tune: 8HP 10TQ Touch Screen - Y WiFi Updates - Y Data Logging - Y Check Clear DTCs - Y 5 Volt Data Logging Inputs - Y Accepts Custom Tunes from CMR - Y Calibrate Speedo for Tire Size - Y Cooling Fan Control - Y Disable Traction Control - Y Throttle Booster - Y Fuel Rich/Lean Adjustment - Y Spark Timing Advance/Ret - Y Idle RPM - Y Top Speed Limiter - Y Rev Limiter - Y Torque Management Adjustment - Automatically Adjusted Disable Active Fuel Management - Y Disable Auto Start/Stop - Y

    What's the difference between the platinum I3 and this one?

    Asked by: Hemi2015
    Part number 8321 is 50-state emissions compliant. The Platinum is non-emissions compliant and you can upload custom tunes.

    I just tuned my 2015 Ram and did not see any torque mgt change options. Also, I thought I saw somewhere or I can make changes with the steering wheel cruise control buttons, is that true?

    Asked by: Roger
    Torque management is already built into the tune, and the intune i3 does not offer the option to change the power levels from the cruise control.
