Hello to all, new to forum and have a few questions. Purchased a used 2019 RST with the 5.3. Not new to AFM but first truck with DFM and Auto Start/Stop.
I installed a Pulsar LT unit, programmed per instructions/videos. Maybe it's me but it seems the DFM delete function isn't working as it should but the Auto Stop/Start functions works fine.
It seems that there is still a bit of hesitation and shuddering when accelerating.
Any thoughts or should I be considering other issues.
Thx
