That's not the wastegate, it's the ECU cutting fuel if your getting what feels like a cut out or surging. It's overboost.
You simply need to back off the wastegate adjustment a quarter of a turn at a time until it stops under hard acceleration.
Adjust the rod so it's longer to open wastegate sooner.

I hope Andrew "lovemyrangie" is still watching this thread, seems to understand what is going on in TD5 turbo world.

My question is this, I have shortened the rod to increase boost which it certainly did, previously disco wouldn't rev beyond 3500 now screams way past 4500 but it now feels like it doesn't want to slow down when I take my foot of the gas! Feels like an age before revs start dropping

Any one have any ideas about that or is it just that I am not used to how it should be?
