DieselSite Boost Relief Valve (BRV+) – 7.3L Powerstroke

Eliminate SES lights caused by overboost while maintaining full boost and fuel delivery with the DieselSite BRV+ Boost Relief Valve. Designed specifically for modified or “chipped” 7.3L Powerstroke trucks, this valve protects the MAP sensor from excessive pressure without limiting actual engine boost.

🔥 Key Features:

  • Stops Overboost SES Light – Prevents PCM defueling triggered around ~25 PSI

  • Maintains Full Boost – Relieves pressure only to the MAP sensor, not the engine

  • BRV+ Design with Gauge Ports – Monitor MAP sensor pressure and true boost

  • CNC Machined Precision Valve – Exact orifice sizing ensures consistent, reliable operation

  • Lightweight & Clean Install – Reduced weight with a compact, professional appearance

  • Mechanical Solution – No electronics, no tuning required

⚙️ How It Works:

On modified trucks, the PCM will trigger an SES light and reduce fuel delivery when it detects overboost at the MAP sensor. The BRV+ vents excess pressure before it reaches the MAP sensor, allowing the engine to continue receiving full boost while keeping the PCM satisfied.

🧰 Installation Overview:

  • Installs inline on the MAP sensor hose

  • Located on the passenger side, running over the intercooler tube behind the oil fill

  • Arrow must point toward the MAP sensor

  • Ports come pre-plugged if not using boost gauges

📊 Boost Gauge Ports (BRV+):

  • Two 1/8" NPT ports included

  • Allows you to monitor:

    • Actual boost

    • MAP sensor boost

  • Ports are plugged from the factory

  • Boost gauges typically include fittings, otherwise use:

    • 1/8" NPT x 1/8" compression fitting

🛠️ Maintenance Notes:

  • Valve is mechanical and extremely reliable

  • If sticking occurs after long storage, apply light lubricant (WD-40 or similar)

  • Pull the ring a few times to free movement

  • Occasional lubrication (about once per year) is recommended

⚠️ Important Notes:

  • SES lights are not always caused by overboost

  • Always scan and verify fault codes

  • There is no code labeled “overboost”

  • If installed correctly and not sticking, the BRV+ cannot fail to prevent overboost defueling

If you’re running a tuned or modified 7.3L Powerstroke and want full boost without SES lights or fuel cut, the DieselSite BRV+ Boost Relief Valve is a proven, precision-built solution trusted across the Powerstroke community.

Filter quality and value
Style: CF11809 Classic
2nd time to purchase this item over a 5 year period. The filter has a rigid frame making last much longer than other paper filters. Perfect fit and worth the cost. Great job filtering cabin and neutralizing odors!

Simple Upgrade That Makes a Real Difference
Style: CF10140 Classic
Installed the Zezut cabin filter in my 2005 Infiniti G35 and noticed the difference immediately. The air inside the car felt fresher and cleaner right away — no more stale air circulating through the vents. The HEPA backing is a big deal, knowing it's actually filtering out dust, pollen, and particles rather than just being a basic filter gives you real peace of mind. The quality feels solid and well made. Installation was super easy, took just a few minutes with no tools needed. For the price this is one of those simple maintenance upgrades that's absolutely worth doing. Your lungs will thank you. Great price and affordable, top choice for replacement in my opinion.

Efficient long lasting. Great Value
Style: CF10735 Classic
These filters (my second one) has lasted me over two years with a little maintenance in between, (removing from time to time to vacuum and shake out the bigger debris.) They do a great job of keeping the cabin air really clean and fresh. 1) Over designed and built (Good thing) installed without effort. 2) Fit and finish is perfect for my 2016 Genesis G80 3) Carbon filter works well but after about six months it no longer absorbs orders, This is excepted especially when I have not swapped it out for over two years. 4) Great value and honestly I should be replacing these cabin filters out ever six months for efficiency and order control. Note: When I decided to replace it the filter held up structurally as the day I installed it. The charcoal beads where all intact as well.
