I just purchased a 2021 Rubicon (2-door) with the manual transmission. I just traded my 2017 Sport and am aghast how gutless my new JL is. I understand the new software "update" (Y01) supposedly detunes the engine under certain conditions related to clutch degradation. Well...those certain conditions seem to "only" occur when the engine is running. :/ Talk about a slug under acceleration! My update was performed before I picked it up as new. Does anyone else have this issue?
