G8 GT / G8 GXP Dyno Tuning

Excelsior Motorsports provides dyno tuning for both LSX G8 engines: LS2 & LS3. We support aftermarket computer systems including EFI Live, Accel EFI and Big Stuff 3. If needed, we can also perform speed density tuning especially in forced induction applications.

The LS3 engine found in the G8 GXP represent the forefront in LS engine technology from GM. These engines respond very strongly to the additional airflow that our engine modifications provide.

The L76 in the G8 GT offers LS2 power with active fuel management for both gas mileage and proven reliability in numerous performance applications. These engines are setup very tame from the factory and produce a great deal of power with performance parts.

Our objective in the dyno cell is to give the customer the most accurate and repeatable diagnostic and tuning evaluation possible. We spent many months of research looking for the best dynamometer hardware and software being produced. We found the latest software and equipment being made in Australia by Mainline Automotive using the latest Windows based software; DynoLog. Our dyno cell has 60,000 CFM of air flow capacity for proper cooling and fume evacuation for repeatable testing. With both systems in place we are able to get true and accurate data to the customer to establish baseline data. Any changes after that can be recorded and compared to the baseline. Besides our EFI Live Software we can use any after market computer software to tune your car.

Due to our unique software, proven parts combinations and years of experience; our dyno tuning has become quite popular. Please book your dyno tuning session or parts installation in advance.
