gdog Posted April 12, 2021 Author Report Share Posted April 12, 2021 Installed the new hot side today. Tuning starts anew. All I can say is epic fail; my guess is it's been melting down for some time.. Link to comment Share on other sites More sharing options...
ChristiaanW200 Posted April 13, 2021 Report Share Posted April 13, 2021 Ooofff that one is pretty bad indeed. no anti lag or such features? Link to comment Share on other sites More sharing options...
gdog Posted April 21, 2021 Author Report Share Posted April 21, 2021 No, no anti-lag "feature" installed. The cat was definitely causing excessive back pressure but no way to know which was the egg and which was the chicken in this scenario (between cat becoming plugged up or hot side housing failing). Also note the BOV had a vacuum leak in it too, so it wasn't functioning properly; am sure that didn't help either. With new housing and free-flow cat in there now, the difference is quite dramatic; feels like a new engine again! Though had to back way off on load request in the tune; as I said, tuning starting anew again. Link to comment Share on other sites More sharing options...
ChristiaanW200 Posted April 29, 2021 Report Share Posted April 29, 2021 i'd say both are the effect and not the cause. i'd check your tune and fit a EGT sensor. both are caused by excessive EGT. Link to comment Share on other sites More sharing options...
