I have a 2015 SRT 392...my friend had a 2012 SRT8 a few years ago and has a Diablo tuner he said he'd sell cheap...
I am posting a picture of it...
I know zero about these and really would never even consider one other than if I can buy it cheap and it will work with no hassel...
Hell...I don't even know what all it does other than add some HP...? LOL I don't have a clue...

It might be outdated and worth nothing, I don't know...

He has the box and instruction...
He told me something about it needing to be "unmarried" from his car...?

What can ya'll tell me about this...???

Someone with more knowledge then me will chime in here but I don't think it will just work on your car.

I think you have to have it "unmarried" from the previous car and then a tune would need loaded for your car.

While both cars are 6.4s I think different tunes maybe even parts were used between the years.

You can’t use it on a 2015+ without buying an unlocked pcm

If you have 2015 or higher you have you have to either unlock your PCM or buy a new one that is unlocked otherwise the Diablo tuner is useless to you without an unlocked PCM you cannot change anything Or tune the vehicle But after that it is totally worth it just as a scan tool if you have a check engine light it will tell you why save you a bunch of time and money and you don’t have to go to the morons at the dealership and I’m not sure on that model about needing to be unmarried But the I3 that I have will work on any Dodge

I would already have one if I was able to use it without an unlocked PCM on a 18...
It's really too bad... I won't do an unlocked PCM until my warranty is gone.

On 2018+ you also need a smart access cable.

This image is from HP tuners but also applies to diablo.

Thanx for the replies but I am passing...
Too much trouble...heck, I love my SRT as it is...
It isn't like it is hurting for power! LOL
If it was a simple and cheap plug and play I would go for it but nah...
Thanx again!
