The only slipping that occurs is when the pulleys are actively changing gear ratios. The pulleys are effectively changing diameter, and therefor the length of the pulley circumference that the belt is contacting. That should mean the portion of the belt contacting the pulleys needs to "stretch" or "contract" a bit as that change is happening. The belt is made of steel bands and segments, so it's not so good at stretching - more likely the segments will slip slightly on the pulley. Another possibility is the two halves of each pulley are engineered to rock slightly with respect to each other - to go slightly out of parallel so that the belt-entry side of the pulley is actually a different width (effective diameter) than the belt-exit side. This would let each successive belt segment contribute to a stairway-like formation as it goes around the pulley. The trouble with that: out-of-parallel pulley halves would have greatly reduced contact area with the belt segments (whose shape is cut to match the pulley vee), which would be its own potential wear issue.
It's unfortunate all the engineers have to sign NDAs - I would love to hear about the challenges and solutions of modern tech.

on the other hand can i have your version of bad injector , and what happen to the car (missfire or something) im deep in a diagnistoc for a p0420 and find out they have tsb for bad injector. but other then that car run really nicely and im not sure i want to change 4injector and a rail for like 1000$
