hey guys

I have a little problem with my xr6T.. It started acting up today sounding different not hearing it spool up as much and the stock BOV making a very loud whoosh noise (not the normal sound it makes this was different)? only time it would go above 2-3 psi was in 2nd gear which it hit 4psi then bounced and surged between 3-4psi? if this is not just a simple boost leak what else could this be???

thanks for your help

yeh could be boost leak mate have you lifted the bonnet and listened??

how new is your exhaust? and what is in it? if you have got it recently and not got a tune you may be overboosting

just a thought im sure someone with more knowlage will be able to help you more

Check all your piping and vacuum hoses, had the same problem n found out it had boost leaks all over the place, a few new hose clamps and problem solved

Check all your crossover pipes are connected properly and make sure you thoroughly check the joiner from crossover to throttlebody.

Heard a few cases where they have little splits that leak like hell.

New silicon joiner will fix that if its the problem.

Nice one - good to hear it was not anything more sinister.

Make sure you get a good quality aftermarket silicon joiner on there and you will not have to worry about the problem again!

Cheers
