Hi guys,

I am installing TiAL 44mm WG's and would prefer to control boost with the Bosch ECU/N75.
I have COBB accesstuner so I can play with the boost maps.

Talked to COBB about this, should work fine but they havent tested such setup.
Anyone has experience with this, controlling ext wg's this way?

 

I have no experience with Cobb but that setup will work like normal as long as you only connect the boost pressure hose to the port below the diaphragm on each wastegate. Make sure you leave the top port open with the banjo fitting installed to help keep debris out.
