GrantDuncan Member 4 Member For: 17y 3m 27d Gender: Male Location: North Shore Auckland Posted 24/02/08 10:32 PM Share Posted 24/02/08 10:32 PM Ford recently put a new ECU in my XR6T as there was a fault with the original computer. Prior to that the turbo blow off valve made a distinct sneeze coming off high revs. It no longer does this. Has anyone else exprienced this or explain what might have changed?

Can you notice a difference in performance? Link to comment https://www.fordxr6turbo.com/forum/topic/42950-turbo-blow-off-valve/#findComment-638124 Share on other sites More sharing options...

Are you running the stock BOV? if so it shouldnt sneeze unless your venting to atmosphere, which isnt a stock setup. If you are relatively stock its possible that you had a break in your rubber seals on the crossover and they replaced it. The sound you could of been hearing is the air escaping from the open wastegate and out the broken seal?At high revs, when you back off suddenly, do you get a TU TU TU TU sound?

ZAP No boost, no bottle, just my foot on the throttle! Lifetime Members 7,935 Member For: 21y 4m 7d Gender: Male Location: Sydney Posted 25/02/08 09:10 PM Share Posted 25/02/08 09:10 PM The sound is normal, but it if Ford has replaced the ECU or flashed a new ECU update it would have wiped your Edit tune.It should say so on the invoice from Ford. This may be why the noise has changed as you are now running stock boost.

If anything the sound is more obvious, but it doesnt change...

If anything the sound is more obvious, but it doesnt change...So why would the sound change? The guys who did the performance tune say it is performing fine and the mechanic at Ford said he had never noticed the Phsssst sound in an XR6T. Odd although mine is a 6 speed manual and he may have only encountered autos.
