    Higher than stock WGDC 2 years ago
    5out of 5stars

    You will read the disclaimer that this needs to be tuned to have lower than stock wastegate duty cycle of about 20-30% or else you will over boost. Well, mine is one of the few oddball ones where it is currently at 25% above stock WGDC to hit target boost and be responsive. At stock duty cycles, the car just felt sluggish and slow. Like others, I have checked connections and hoses a handful of times to make sure they are correct, which they are.

    Better boost control 3 years ago
    4out of 5stars

    This is definitely a must-have part to support other power mods. For some reason, my WGDC's with the COBB boost control solenoid are pretty much the same as stock. After everything I read, I was expecting duty cycles to be lower than stock, but not the case. I double-checked and triple-checked the installation and hose routing, and it's all hooked up properly. Had to tune wastegate duty cycles around 55-70% to reach 18psi on 2012 STI with stock turbo, COBB downpipe, COBB SF intake, Tomei UEL headers. After some tuning, I can hit 18psi at 3400 rpm without spiking, and smoothly control it over the rev range. Caution- it's quite difficult to reach down to the wastegate actuator to remove the stock vacuum hose and install the new hose and zip tie. It helps to take off the top mount intercooler.

    Easy install and controls boost great, no fluctuations in boost like the restrictor pill 2 port style. Nice and smooth boost kind when logging. Another great mod by RSD!

    Cobb 3port boost controller selenoid  3 years ago
    5out of 5stars

    Everything came fast and as described the install was a little bit of a hassle but after doing some research it was a breeze. If you're not mechanically savy you're best bet is to take your car to a shop to peform the installation. DON'T FORGET YOU NEED A TUNE AFTER INSTALLING THIS PART!!!

    A must for a protune 3 years ago
    5out of 5stars

    Whether you go with Grimspeed or Cobb you want your tuner to precisely set your target boost. I went with Cobb solely based on there name being associated with Subaru's. If your adding basic bolt on's such as intake, downpipe, up pipe, headers, tgv's deletes, etc make sure you add this to the list!
