Cheers RONNIE but does the turbo boost pressure sensor need the MAF to work properly?? Wat is happenin is i have a problem an wen i unplug the turbo boost pressure sensor it goes away but i want to determine whether it could be the MAF that causes the sensor to not work properly??? Are they inline of each other electrically?? PS im strugglin to use that link m8 any advice???

They'll be separate all the way to the ECU.
Unplugging any sensor will usually cause some change in the running, and in your case, it will use a default emergency value for the boost pressure, i'd expect it to keep the boost pressure low in a case like that as it isn't able to spot overboost conditions.
