ive got a bf mk 2 xr6t, its manual,centre muffler removed,n bmc filter, it pulled 194rwkw stock and on the 8psi tune pulled 234rwkw, I didnt have it on the rollar for the 10 psi cause the afr were way to high and got told not worth pushing it for a power run, now my question is im getting my custom tune done next monday and wanted to know should I just stick to 8psi or go the 10psi ?? if I go the 10 will the clutch last long? and I dont want to change my injectors cause trying to keep it stock as ill probably sell it soon enough but just really wanna see how it goes with the custom.....
