DynoJet Services My Car Chip Sheet Dyno Run Videos

GRC Performance offers in house dynamometer testing and tuning. Our Dynojet model 248x is a 2 wheel drive chassis dyno capable of handling vehicles with up to 1200 rear wheel horsepower, and speeds up to 200mph. The 248x can supply customers with vital information such as horsepower, torque, air fuel ratio, boost levels, fuel pressure, and mph, as well as being a diagnostic aid in finding drive-ability problems that only occur at speed.

GRC Performance offers individual dyno runs to all customers with 2 wheel drive vehicles, front or rear. With each session, you will receive a color graph of your vehicles torque, horsepower, and air fuel readings. Optional boost and fuel pressure graphs are available at additional cost. Selected data must be requested before dyno sessions begin.

Customers may also purchase dyno sessions by the hour. During hourly sessions, customers will be allowed to make as many runs as they would like, performed by a GRC Technician only, and also any planned minor adjustments. Customers must supply all their own tools, tuning software, and labor for adjustments performed. Sessions begin once the vehicle is strapped and ready to run.
