Performance Services

Performance Tuning

Chassis dyno tuning of Carbureted vehicles: As part of your carburetor tune we will change metering rods, springs, jets and adjust carburetor settings for best drivability, horsepower and fuel mileage. We will also "dial in" the spark curve. This tuning will make sure your engine gets the proper air/fuel mixture and spark timing under a variety of conditions. 

Chassis dyno tuning of EFI: Performance expertise with GM LSx EFI engines & aftermarket EFI applications: (call for details). We will custom modify your PCM spark & fuel settings as needed for the best possible drivability, horsepower and fuel mileage. This tuning will ensure your engine gets the proper air/fuel mixture and spark timing under all conditions. Let us help you get all of the horsepower, fuel mileage and enjoyment you want and deserve!
