Alright I have been reading a lot on the saab turbo setup, but some things im not sure about and was wondering if you could help me. First is this the correct turbo i know there was the high and low pressure setups not sure if they used the same turbo Clicky . My other question is i know the turbo is set for a specific amount of boost. But how do you control the boost on the stock BOV or do u need to use a separate BOV and just not connect the vacuum lines to the stock one. My last question is where would i get the new TMAP Bar and connect am i able to buy it at the Chevy dealer?

You can simply use a boost controller to regulate the boost by adding it in line from the compressor housing to the actuator. The Garret turbo is the low pressure model.
