sounds good. from what I hear about the probe, people say they can see the exhaust temp drop 200 degrees between shifts, then rise back up again...which leads me to believe that it has a slew-rate of around 200-deg per second...none the less, it is cheap and should be pretty accurate

Weavil - SCRAM Performance has one now, along with a wide-band. I believe they installed a setup that physically attaches to each wheel, unlike a dynojet.
