hey guys so i have a greddy profec b spec 2 an no matter how much i play with it its not changing the boost the car is only hitting .75 bar its reading numbers an all that good stuff but it wont change the boost im out of ideas only one i got is that it isnt hooked up all the way. this system was not installed by me. any help is appreciated thank you

 

Take it back to your installer?!

 

lol the car was bought like this he said it was down tuned an im figuring for the down tune he unpluged stuff

 

sounds like its running on only wastegate pressure
trace the lines off the turbo and wastegate actuator and make sure they are hooked up to the boost control unit under the hood
