dyno runs, Brian performed a complete tune up as well as a total diagnostic check of all sensors and settings, right down to the base ignition timing. Brian even made sure the stock air filter wasn’t clogged. Confident the L98 was up to specs, Brian put the Corvette on the dyno and established a benchmark of 194 horsepower and 260 ft-lbs of torque. These readings and the ones to follow are averages taken over a 3000 - 5000 RPM range. Average readings, opposed to peak values, are a far better representation of power gains. Simply publishing peak numbers tells you nothing about the overall performance of the component or modification.

Stage 1
     Brian started at the front of the induction system and worked his way up stream to the throttle body. The stock paper air filter gave way to a high flow K&N air filter and the factory filter lid was opened up exposing more of the filter to incoming air. The mass airflow sensor (MAF) was next in line. There are really only two things one can do to the MAF. Removing the screens is first and nets the greatest airflow gain. Second is cutting out
