I've got 330, but I drive with mechanical sympathy in mind.Depends on how hard you drive it, and if the tuner has upped the pressures (think that's what they do?)

Saski Member 68 Member For: 16y 8m 2d Posted 24/01/14 07:43 AM Share Posted 24/01/14 07:43 AM Mine lasted 4+years after its tune with firmer shifts. 260 rwkw with trans cooler. Only failed last week due to recent melbourne heat which stuffed the converter. My btr lasted 235k of which 180k was while tuned, some 25 passes down the quarter. All other times it was sensible driving. Never had to be opened, just an annual fluid change.It lived a long life....rip Got a rebuilt unit now Link to comment https://www.fordxr6turbo.com/forum/topic/86866-ba-xr6t-gearbox/#findComment-1451781 Share on other sites More sharing options...
