ELIMINATE the SES light caused by OVERBOOST.
NOW WITH BOOST GAUGE PORTS TO MONITOR MAP AND ACTUAL BOOST!
The SES light for overboost will come on at about 25 lbs. causing the PCM to decrease fuel delivery attempting to control the boost. This condition usually occurs in "chipped" vehicles. Our BRV+ (Boost Relief Valve Plus) will relieve anyexcess pressure to the map sensor while allowing the engine to receive full boost. No more SES light and full fuel delivery through all RPM and boost ranges.
The boost relief valve is installed in the line to the map sensor. This line is located on the passenger side of the engine compartment and runs over the intercooler tube right behind the oil fill tube. Make sure the arrow is pointing towards the map sensor.
By designing a CNC machined valve, every BRV+ will work flawlessly and exactly alike. Every valve, in order to work correctly, MUST have a precise orifice sized for proper volume control as well as the blow off valve. We have machined the BRV+ so that there is no chance of human error when creating the small orifices necessary to make the valves work. You get quality precision pieces, every time. The new valve provides a clean looking installation with less weight. (5.1 oz. vs. 3.7 oz.)
BRV+ ports come plugged in case you're not using them. To install a boost gauge, simply remove one plug and install your boost fitting. Our pictures below show the BRV+ installed with a boost gauge in each port. This is done to measure your actual boost and what the map sensor sees at the same time -- this requires two boost gauges.
Special Note: Both ports come from us with plugs installed. Your boost gauge should come with the fittings needed to install a boost line to the valve. Should you not have them, or your gauge did not come with them, these can be obtained at any hardware store. Simply ask for a 1/8" npt (national pipe thread) x 1/8" compression. This is a standard plumbing fitting.
