The HOA 3 Port Boost Control Solenoid is a great alternative to a external boost system, or to a Manual Boost Controller. This solenoid is a direct OEM replacement that includes a Plug and Play harness (no wiring needed). It is controllable via Stock ECU, when being tuned using the stock ECU.

This Solenoid unlike stock will control boost well beyond 40PSI, and will help with boost creep that is common with manual boost controllers.

This, along with the required tune, has been my favorite mod so far. Went with an XPT tuning stage 2.5 map, which requires this BCS... difference is phenomenal right off the bat. Spool time on my VF39 was decreased massively and everything just feels more solid. I would definitely recommend this product. Word to the wise: this doesn't include any sort of bracket, so you'll have to kind of just rig it up some how. I filed down one of the holes and used preexisting screws and nuts. Works fine. Also, make sure to pick up... eh... 6 or 7 feet of 4mm (5/32) rubber tubing from somewhere like NAPA. You'll need it for the install if you're doing it yourself. Lastly, this EBCS is the same thing as the Prodrive and Tactrix EBCS. The only difference between this and the GM EBCS that you can get is that this includes a wiring harness that is very useful and speeds up the install significantly.

One of my favorite mods

Without much knowledge this product can seem like a silly modification at first glance, but improved boost control is extremely noticeable when installed. You can see it on the dyno charts and feel it with your butt dyno.

I purchased based on my local tuner's suggestion and the price point was much better than the competitors. I would recommend this to others.

  • AnswerQ: stock turbo  donnatae 3 years ago

    its ok to install this on a stock turbo

    • A: This will work with your stock turbo but does require recalibration of the parameters on your cars computer.

  • AnswerQ: Boost issues  ctom24 4 years ago

    Hi right now i'm having some boost stabilizing issues with my current BCS and the wastegate duty cycles are somewhat wavering with either the stock map or the stage 2 OTS map with the accessport. With this and a tune will that help?

    • A: It is hard to say without being able to diagnose the vehicle to determine if your stock boost solenoid is in fact the culprit here. The HOA solenoid is much more responsive than the stock solenoid so by installing this unit and tuning your car you should have much better control of your boost.

  • AnswerQ: fit with apexi avcr-r  massimo bosisio 4 years ago

    Hi, fit on apexi avc-r ??? regards Massimo

    • A: The Apexi AVC-R Boost Controller comes with it's own boost control solenoid. This solenoid has not been confirmed to work with that boost controller and is not necessary for the Apexi controller.
