Hey all,

Been here for a while, mainly lurking, just thought I'd get some ideas before I start pulling things apart on my car :)

I have a 02 ba xr6t, tuned to 360rwkw and when in low rpm situations and then apply WOT, the intake noise rises then Become a bit higher pitch and Rpm climbs... Then Just slows and stops.

It sounds like either the BOV is leaking or have a boost leak, but I thought that with either the revs would still climb, just a sh*tload slower?

Unless I have a over boost problem and engine is closing throttle plate or pulling timing?

Have no boost gauge at the moment but am going to book in with tuner to check... Just thought I'd ask if anyone has had any similar problems and if they could share experiences :)

Problems occurs in 3rd and 4th mainly, as I said at low rpm and heavy load. Has happened once or twice in 2nd and never In 1st.

Cheers fella's

Damien

Cheers for the thoughts mate, I was leaning that way since it doesn't jerk or hesitate or skip etc... Just slows its revs and then doesn't rev any higher. Points toward engine intervention in the form of retardig timing but anyone else with some other ideas would be a great help!

mines a fg when it hits over boost the car just has no power (goes into limp mode) until you turn ignition on and off. Do you have a code reader or xcal3? If so grab the codes off it.
