I have a 2019 dodge Challenger GT and was wondering if I could use the double bypass from my Tazer tuner to plug in the Diablo tuner without doing a pcm swap. Do i have to do a PCM swap to get the the Diablo to properly tune my vehicle?

I believe you will need to get your PCM unlocked before you can do any tuning.

Ok thanks. My modded PCM comes in a week. So im just being impatient with Dodge's dumb security precautions. If My Tazer needed a double-bypass to 'bypass' security software and tune for RWD, would the Diablo not be able to tune hp aswell through the double bypass?

Welcome to Challengertalk ;) You need an unlocked PCM to tune on 2015+ always. The bypass should work for your tuner as well. The Tazer makes no PCM modifications, all in the BCM I believe, so apples and apricots ;)

Umm, A Guy are you sure about that, Tazer? I am pretty sure that's what Challytatum uses to tune. The OBX and alpha software only do the BCM.

I will not say that I am certain, but how else could a Tazer make changes that don't require it to be left plugged in, without an unlocked PCM? The Tazer does not tune, it only enables features already available on other trim or with purchased packages. ChallyTatum uses HP Tuners to tune

Your right, my bad. I was thinking Tazer was HP Tuner for some reason and I was also like WHAT is up with A Guy he would know this.
