Overboost problem

Ok fellow turbo owners. The issue that has plagued our family XPT4 for a year as of today and has been to the dealer 9 times now and every single time it is there for 2 plus weeks every single time. It is now back at a different dealer to have a different set of eyes on it per Polaris?s request. The dealer and Polaris is only throwing parts and guesses on how to fix the issue of the overboost code of 1127 and the last two ride it has thrown serveral other codes and put the machine in limp mode. They have done waste gate adjustments, replaced the blow off valve, reflashed the ECU serveral Times, checked all hose lines, changed the T-bap sensors, and as of last Thursday a brand new ECU. Which i had hoped had fixed the issue, but when I plan and go to Dumont this weekend after renting an rv and getting all of the necessary things to make a 3 day trip only to end after only 4 miles in. The rzr threw the 1127 and than threw 2629 and 3 under that number and putting the car into limp mode and also not having any 4wd after the new ECU on top of that. Just to possible save the trip I disconnected the battery and touched the leads together to see if that would reset the codes and to no luck we left after only being there less than 24 hrs. And out a lot of money, because Polaris and the dealerships cannot figure out our machine.

My question is after this long discourse that I wrote. Is there anyone else that has had this much problem with there turbo and what can I do or am I at the mercy of polaris?s BS?

We are completely out of patience and pissed off about how much money and time has been wasted on something that I am still playing for. And the lemon law in Nevada does not cover ohv?s.
Please help and also most importantly thank you in advance!
