You could just say you don't know. Thanks for your take on it but
Sounds like another product is going to hit the markets.

simple it is a coouple of other sensors doing it which i believe i have nutted it out as i havent had a over boost since i fixed mine
more testing happening

A turbo is a mechanical object, a vgt just needs to be manipulated to bleed boost earlier. Don't know why we need to be all cryptic about it

I'm with you
There has to be a logical answer to what is going on

Are you two serious??
There's nothing cryptic about it!!
It's already been mentioned why it happens a few pages back.

In stead of being idiots can you link the specific post?

It's simple the ECU believes the turbo is overboosting and causes a limp mode.
WHY?
Because it's a VGT turbo and it measures the amount of air it consumes over a period of time under full load/100% throttle position and has a built in safety measure to stop the turbo from self destruction.
It's really quite simple.
Those that fit bigger exhausts encounter the problem more reguarly, and in a shorter period of time, because it can expel gas quicker and the limit is reached sooner.
Various sensors, as I already explained, are involved in the ECU making that decision.
It would be stupid of me to tell you what voltages, which sensors, how we unlock it, until it is fully tested.
ie. We risk engines of people that have a clue what they are doing, have extra monitoring equipment in place, as well as know what the risk is.
//I suggest you go find a nice long hill and go hold your engine flat out (do not take your foot off the throttle hold it down)
You will discover yours does it too. They all do it. Once you discover the time it takes, you can then use a throttle blip method to avoid the error from occurring. This may be annoying to some but is an effective workaround until the long term solution is finished.
Real cryptic.
