yer it is when i drive the car that there is no boost...it has a boost gauge and has boost controll all wired and hooked up right by the mechanic..the car will drive ok till it gets up to were boost would kick in and wont open up...no boost... it wont even rev but when it is in netural it will rev.. i have checked.. all the intercooler piping, the intakes for rags that may have been left in the piping also the turbos to make sure they are spinning and not ceesed up, ive checked the lines.. its a sad situation as i have just spent 10k on getting the motor into the car running and 5 hrs before i pick it up they ring and tell me there is no booost.. so i picked the car up and drove it home and now it sits in my garage till i can sort the problem out.. not happy..
