Physically active adults (and athletes) often have a resting heart rate slower than 60 BPM but it doesn't cause problems and is normal for them.
Using technology similar to the Jet PCM, the Jet module provides the ultimate in power tuning. Point-by-point air/fuel, ignition advance, transmission, and various other tuning points provide performance gains and, in some cases, improved fuel economy.
