2016 Procharged Ram 5.7

Have a 2016 Ram with the 7 psi procharger kit on it. Has the supplied tune from procharger by diablo on a diablo pcm.

If we where to use HPT, would it just be the 2 credits? I wouldn't need to send the PCM in as it's already been "unlocked" by diablo, correct?


I'm getting a wierd issue where boost is falling off in high gears, I'm suspect to think it's the torque management pulling the throttle body closed. Anyone have any experience with this?

A few months ago I tuned a 2016 5.7L Ram that we procharged, we used a Diablosport unlocked PCM and it will only take two credits to tune the PCM. I had an issue with boost dropping a bit in high gears too but after talking more with procharger I figured out that the drop in boost was partially from aftermarket headers and we were having a bit of belt slip with the original tensioner setting.
