  1. Review: Full Throttle Speed Scanmaster

    For people who want to know what their car is doing all the time, the scanmaster is irreplaceable. After using it for only a week, you get so used to constantly checking the status of the various parameters that if you remove it from the vehicle you almost feel like you are driving blind...

  6. Boost Spike vs. Boost Creep

    Since these two terms are very commonly used in describing turbo/engine behavior, yet they are not always understood correctly, I wanted to attempt to clear them up.People often mix the two up, or even interchange them, when they are in fact two VERY different things.Boost Spike: Boost...
  7. Engine Limits - Psi, CFM, or horsepower?
