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.
