You may need a boost controller. The car does not come with one. Do a search on boost controllers.

If you had 11 psi before you took it in the shop, and you have no boost controller, then there is something wrong. Maybe the shop didn't hook something back up. Take it back to them.

no see they turned the boost down on the turbos on purpose. isnt there some way to mess with the wastegate and turn it up iv heard?

Do you have a boost controller? There is no way to control the boost by simply turning a ****. Its controlled by the ECU duty controlling the waste-gate solenoid, meaning that they'd need to remap the ECU (assuming its the stock unit) to do it.

The wastegate is controlled entirely by the ECU, but you can get an aftermarket boost contoller to override (i.e., interrupt) the signal from the ECU and have boost set at whatever level you choose.

i dont have a boost controller and it is the stock ecu i had heard something about messing with something on the wastegate to change the boost. thanx ill go back to the shop and get them to do it since im not planning on getting a boost controller quite yet.

you shouldnt run 11psi on the stock ecu
go for 10psi

and yeah there is a way to do it without electronic signals and the ecu lol its called a manual boost contoller duh

ok what you want to do is find the 2 nipples coming off of the front turbo housing. One of those..i believe the right one is going to yoru wastegate actuator...the actuator on top nearest to the hood of the car. Youll need to take that line off and see if there is anything such as a pill in the line. if so then take it out. and you can go home depot and get a valve that controls airflow from the plumbing section. Put it in that hose and then reconnect everything. When you have it open all of the way so that all teh air can pass by you will get 7-8psi as you start to close it and restrict the airflow your boost will raise. Its very simple but be careful because you dont want to mess up your engine by getting too much boost. Also remember that your boost will increase with every gear.

good luck bro

There is a way to controle boost manualy by adding a manual boost controler but you said you didn't have a boost controler.
That's what they been trying to tell you!

Make new pills with holes sized to do the job . You can change the spring in the actuators to a stronger one . That takes machine work and can be done .
