Turbo Engine Boost Controller Kit, 1-30 PSI Aluminum Alloy Car Universal Adjustable Turbo Charger Closed Loop Manual Boost Controller Engine Boost Controller Pressure Regulating Valve

Used parellel with n75 on my 1.8t for overboost control and I can't think of anything that is better value for the price, work fantastic

Everything worked great, used it for about 3 months ranging from 10-20 psiNo complaints especially for the price

I used this to regulate the pressure going to my exhaust cutout. It does work as I needed it to, but it quite large and heavy for what it does.

Garbage no orings, had to buy my own and had to use plumber tape to fix issue, leaks out the wrong whole didn’t work out of the box

So I threw this on my 5.0 and hooked it up backwards. It was such a stupid mistake but it took out my engine. But it is made well. Just maybe some arrow stickers or something would help.

Beautifully made controller. Would appreciate some more instructions.

Just dosent seem to have a very fine degree of control. It's either too much or too less boost. Whish it had more hose

So I bought this with the intent of using it. It looks really nice, but doesn't seal at all. I took off the fittings and ensured the orings were there, put PTFE tape on the threads, all in hopes that it would work. I decided to try it out with my MItyvac, and thankfully I did. It would not hold vacuum. I pumped, and it dropped immediately. It's not worth it. Don't waste your money.
