Hallman Pro Boost Controller Kit - Black

Controls boost. I have it inline on a vw tfsi to limit boost until engine is broken in and to help hold boost longer per gear once that happens. Read nothing but good and so far Im happy.

My last Hallman Boost controller lasted 15 years without issues. Reliable consistent boost controller.

It's very large. Notice consistent boost levels. What complaints I have can be fixed with adjusting my installation. Done multiple boost controllers on different set ups, and this is a solid one. Small fast boosting turbos might look into integrating soming to prevent boost spike, but I expected that. I have no regrets with the purchase.

Best boost controller on the market

Holds boost well and price is great!

Build and parts are high quality. Only thing is the controller itself doesn’t work, or at least the one I got. Even with controller completely closed I’m over boosting which I don’t think should be the case? Still trying to figure out if maybe it has to do with my wastegate.

Fast and easy install, works perfect

It’s made in Ohio, quality is top notch, and it works. What else do you need to know.
