How to Build Up Boost in a Turbo Diesel

Determining Your Turbo Type
1. Research the type of vehicle you own and the turbocharger it is equipped with. Turbochargers and boost management systems vary by model. Determine the maximum safe amount of boost for your engine, per the manufacturers recommendation.
2. Establish a way to monitor the boost produced by your turbocharger. Purchase and install a boost gauge to monitor the performance of your turbocharger and ensure that you do not produce more boost than recommended by your vehicle manufacturer. Boost is measured in pounds per square inch (PSI) and gauges which read up to 60 PSI are available from various automotive performance companies.
3.
Stock tachometers will indicate unsafe operating ranges with red markings.
Locate the RPM gauge, also called a tachometer, on your dashboard. As a stock feature on vehicles, this gauge is normally located on the dash panel near the speedometer.
4. Press down on the accelerator and monitor the tachometer. As the revolutions per minute increase, monitor your boost gauge. Boost will increase as RPMs increase. Operating your vehicle at boost and RPM ranges outside of your vehicle manufacturers recommendations for prolonged periods of time is not recommended.
