I have a 2019 D2 Ram 3500 high output with the Aisin transmission. The PCM currently has version 52.19.05.00 52401932AH.

I am looking for a stock tune for OS version 52.19.07.00 52401932AI with the asymmetrical CP4 pump. Based on the statements in TSB 18-059-20, I believe there are actually two stock tunes (one for the symmetrical CP4 and one for the asymmetrical CP4).

Thanks,

Alan
