Anyone use a diablo tuner?

I think I remember reading somewhere that if your truck is 2017 or newer you have to get the ECU unlocked to do anything with them

I think it may even have been 2015 or newer

The company I was dealing with (or trying to) offers and PCM swap kit, so it would come with a tuner and an unlocked PCM

You'd then have 14 days to send the stocker back
I was planning on buying an extra PCM off ebay and sending that back so I could keep the stocker as a backup, but the whole thing became a moot point since the diablo tuner is incompatible with the 2500 5.7


I called holly and they suggested a pulsar unit, so im going to give that a shot
