Got an X3 capa tuner yesterday and tuned the bf xt6 to capa's 10psi tune. Very happy with the performance but concerned when I saw the boost gauge sitting on 13psi (doesn't spike and drop back but holds the 13psi). The car has only had a f6 snorkel and k&n filter added. Any ideas what could be causing this? What negative effects to the car could arise if I left it running 3psi over the tune??Thanks, Link to comment Share on other sites More sharing options...

Just one of many reasons to be wary of generic tunes..... Link to comment Share on other sites More sharing options...
