Performance
With the GrimmSpeed Stage 1 Power Package and a tune, expect to see a decrease in time to spool, rock solid boost control and an increase in torque and horsepower, The Electronic Boost Control Solenoid keeps boost in the system instead of bleeding it away like the factory configuration. This, coupled with its extremely fast and precise response, makes for an invaluable tool for tuning your boost curve. The Cold Air Intake decreases restriction before the turbo's compressor. This decrease in restriction increases compressor efficiency, which builds boost pressure faster and higher.
