Universal Aluminum Adjustable Turbo Manual Boost Controller Fit All Cars Black

Works like it should. Easy to install. On a 8psi wastegate spring. This helped net me 15psi. So far so good. Teflon the threads and no leaks

Cheap as cheap comes. Absolutely bad quality. Terrible design. Doesn’t function properly. Easy to install, yes but easy to break. Didn’t even get everything out of th box before it fell apart on me. Beware. Don’t use this cheap junk and blow up your car. Get a good quality and name brand. Save your time and spend the money on quality.

Worked as advertised, on my set up (gt45 350 sbc) 1 click is about 1 psi, so don't go cranking it up too fast.

This controller worked perfectly when my setup

Probably does adjust boost, might caused boost cutoff my 98 Eclipse. Lowest setting was 15-20lbs of boost. Couldn’t go lower

Simple easy to install and works as it should. Cheap boost control. Can’t ask for more.

Test it first! I took it apart is I couldn’t get any pressure through. They put a check valve in it and the spring was jamming the ball so no pressure would go through also the metal filings were still inside it from tapping. Quality is low but if you take it apart clean it and trim the spring it does its job. The tee is a joke don’t use it. I was able to adjust my boost 3 clicks for 1 psi. I would buy again but you need to test and spend some time with it. Don’t just throw it on and expect it to do anything but keep your waste gate closed. Might as well pull a tilito and pull the line off

Works like a charm!!! Now I'm boosting to 21psi!!!
