Power Driven Diesel has developed a new boost controller for internal waste gate control. Unlike current manual boost controllers, PDD’s new Turbo Tuner does not have a bleed orifice, which means it can be mounted in the cab. This allows users to adjust their boost levels up or down on the fly by simply turning the knob. The Turbo Tuner prevents the waste gate from opening until boost pressure surpasses the knob setting, which eliminates early waste gate opening to increase spool-up. Precise waste gate control is very useful in tuning twin/compound turbo setups since, in general for towing, less waste gating yields better EGT control and for big power, more waste gating is required. With the Turbo Tuner, waste gate adjustments can be made from inside the cab.
