right heres the problem when the car starts to boost the turbo will cut out then boost again all in 1 gear then when i change gear happens again any ideas people other than just saying the turbo`s nakerd???

 

split vacuum pipe?

 

check all the pipes i had exact same problem when i checked i had a split pipe from the turbo to solenoid, mine was the one to the left of the tmic looked like the intercooler had rubbed against it
good luck

 

mines bin doin a similar thing, just gets onto boost and cuts out then gets back on again, its been suggested to replace the MAF sensor as the ecu only recieves info from this below a certain rev range, i.e boost range not sure how much truth is in there like but just a suggestion
