The issue does not occur under acceleration. It was the result of excessive vacuum, which only occurs under engine braking.I just had the TSB done and I’ve noticed that if I put it in manual mode and downshift through the gears, the RPMs rise, but I have very little, if any, engine breaking. My fear is that I have issues with oil getting past the piston rings and what they have essentially done is limited the oil consumption to just occurring while accelerating and significantly reduced it when decelerating, hence, I will burn half the oil and remain within their ridiculous oil consumption specs. Thoughts?
I have not noticed any perceivable difference in engine braking after the software update. It’s not like it’s holding the throttle fully open; it’s just cracking it enough to prevent excessive vacuum from building and drawing oil past the rings.
