With my aftermarket boost controller i cant controll the boost. But when I hook it up to the factory boost controller it works fine and run around 14 to 15 pounds of boost.
Its a MBC that work's just fine on the stock turbo. Then I put the VF39 on the boost controll wont turn it down. I had the MBC turned all the way off and the car was still wanting to over boost. :beatentod
Before I change the turbo on my car it was runnig around 18 psi with the MBC. The Mods Are full Exhaust Downpipe and Uppipe and MBC the car was running a 13.5.
Boost controllers arent usually a good idea early on in the modding phase of the WRXs. Especially if you are just slapping it on there and turning it on/up yourself. Search around about it.
I'll sell you mine for cheap once I figure out why my ecu isn't sending a signal to the bcs.
