Check out this iPhone application. We'll be testing it the next few weeks...

 You simply plug the small DashBoss Bluetooth device into your truck's diagnostic port and use it as the ultimate performance tool...

Some things you can do with the app:

*Run virtual quarter and eighth-mile times (as well as 0-60 mph)

*Set alarms for individual parameters you want to monitor (temperatures, speed, etc.)

*Read and/or clear diagnostic trouble codes

*Read/monitor any parameter your truck's computer can

*Calculate horsepower and torque in real-time

*Data log key parameters for later review

*Upload captured data to your desktop

We'll let you know how our testing goes in the January issue.
