    Rated 5 out of 5 by from A-M-A-Z-I-N-G I bought this once my 2018 went over 36,000 miles, and I couldn't be happier with just the can tune. So glad I did it and the installation was easy with minimum tools needed. Highly recommend this product for any 5.7 Hemi to bring it to life.

    Rated 2 out of 5 by from Process issues & can’t register inTune3 Sooooo, you aren’t told that you have to wait for the unlocked PCM after you receive the inTune3. Then, you aren’t told that you have to also install a “kick panel cable” on 2015 models and up ( got a 2021 Charger). Also, you can’t register your inTune3, because when you try to register, it ask what year model car you have and the menu only goes to 2019, it’s 2022! Forgot that you have to get some information off of your current PCM as part of the “PCM Swap”. That is forgivable, but wasn’t told up front. Will give a 2 star instead of a 1 star, because my last car (2010 Challenger) Diablo Tuner was great! I still think DiabloSport’s products are good, just disappointed in my experience 12 years later. Is this Holley’s fault?

    Rated 1 out of 5 by from Too Many Bug and Glitches I bought this device for my 2019 Dodge Charger Scatpack about a month ago and I still haven’t got it to update. FYI: If you can’t update the device then you cannot start the vehicle with the unlocked PCM or install any tunes. I have taken every procedure to fix the problem but I am left without a solution. I have tried to call customer service twice and in total, it has taken me 2 hours just to talk to someone. Even then, my problem still wasn’t resolved. The device itself is very janky for how much you’re spending. It always lags when you press a button and takes a while to display what you pressed. My solution is for DiabloSport to send their devices updated so other customers do not have to be in the position that I am in right now

    Rated 5 out of 5 by from Punchy! Bought this almost two months ago, and finally had time to put it on. Didn’t know what the heck I was doing until I realized I needed the bypass valve to use it (silly me). But once installed with the 91 octane Diablo Tune, this dang RT is amazingly fun to drive now! Definitely feel the increased torque, cold starts are ALOT better on stock active exhaust, and wheels spin literally everywhere! Corsa catback is next to add on and I’m definitely excited to see how this thing acts up!

    Rated 4 out of 5 by from Amazing The only reason I gave this a 4 stars was because of the canned tune. I am positive I lost performance. I have a T/A 5.7 and they are tuned differently than the R/Ts from the factory. I could tell huge gains as far as gas mileage but my performance suffered. That is the only bad thing. The device, the support, everything about this experience has been great! I am so happy to be able to tune my car to my specifications.

    Rated 5 out of 5 by from Really woke up my '18 6.4L Challenger I did the headers/cats/3" exhaust and 85mm throttle body and got more power.. THEN I got the tuner and installed the "canned" tune and of course, got more power ... AND THEN I had a 3rd party (HemiFeverTuning) write a custom tune for all my mods and holy cow! You're already gonna be many hundreds into the tuner and unlocked PCM, spend the few extra bucks for the custom tune as well!!

    Rated 5 out of 5 by from i3 on 5.7 RT I can honestly say I am very satisfied with the tuner and the results. If you’re on the edge about it don’t be. It will definitely give you a noticeable gain. I could feel the increase in power in my RT right away. The PCM swap process is painless as well. Once you get a custom tune it’s even better but then tunes that came with it were great and will definitely be noticeable!

    Rated 1 out of 5 by from Intune i3 I have updated my i3 & it is still failing to read every time I try to tune.

    I am planning on boosting my charger, probably next year. if i use this pcm&tuner on my stock setup, will i have to send it back in later to get another one when i boost it, or can i tune my car with the supercharger on this same pcm?

    Asked by: 2020SPWB392

    Will this work with a 2017 Dodge Charger RT?

    Asked by: midswag

    Does this come with the unlocked PCM and multiple tunes

    Asked by: Anel

    What kind of performance gains can I expect installing a Diablosport inTune i3 Platnum tuner on my 2018 Dodge Challenger RT scat pack? Current performance upgrades include K&N air box and mid muffler delete.
