VF39 Turbo on My 2002 Wrx

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.

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.

If it's worth doing, it's worth overdoing

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.

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.

with wrx you need EM to adjust the boost, so get a EM before you wreck something.

I'll sell you mine for cheap once I figure out why my ecu isn't sending a signal to the bcs.
