My 2010 RT automatic was still climbing at 6200 on the dyno when the operator shut it down.I get slightly better times shifting 2-3 at 6000.1-2 shifts are at 54-5700 no matter how you program it.Fastest I've ever gone is 92, and that was in mds mode seeing how fast I could go with eco on, traffic made me let up. Another member here mentioned he had got to 100.
