Might be another fact that turns out to be complete carp but when I ran a search ages ago on boost solenoid cleaning I read about replacing a pipe from the solenoid which improved the boost curve.

Someone said they replaced said pipe with a lager internal diameter and also the T piece and the following hoses connected to it which made their car feel quicker.

There is and its quite big in America. But doesnt make a huge difference.

Its the hose with the restrictor in I think.

Ill dig out the page.

There are loads of changes you can make, it just makes more overboost in higher gears though. There is a risk when you trash it hard on a cold wet day that the overboost will trigger boost oscillations.

CustomScoobyIOM - Cheer mate I'd be interested in seeing what I have to do.

John Banks - Whats boost oscillation? I take it its not a good thing.

I don't really thrash my car and I would say honestly that my car rarely passes 6k or even gets close to it. Just like a car that pulls well - if that makes any sense.

Leave it alone then.
