I have replaced the MAF with a new one but am still getting the ABS and PSM off errors on high RPM and high speeds, the car is boosting to 1.3 Bars without any other issues, i think its because of the tune, Tony asked me what type of wastegates i had in the car and it was the stock ones when he did the tune, maybe he needs to send me a new program or tune to go along with the new EVOMS wastegates.
