With the sensors installed we strapped the pickup to the dyno to simulate a real world road test (this also allowed us to get some horsepower and torque figures to illustrate the results of the tests). This offered all the benefits of a test with the drivetrain under load at cruise speed without actually having to drive the truck at a steady speed on a long stretch of road. Call us lazy but it enabled more data to be collected in less time, though we should stress the FAST kit is designed for mobile use. The FAST meter is ideal for tuning to achieve the optimum air/fuel ratio, but it doesn't give horsepower figures.
