I beleive it is around 1100 and you need something to read it ie one of their boxes. saw it at sema very cool stuff! and not made to be run on a jackstand it is for real world tuning. stays on your car and you drive around or race and receive real time hp and tq numbers.
You could take your car to the track and make dyno runs at the same time, the 1/4 mile would be your dyno run. It would be perfect for someone tuning their own vehicle. It would be neat to see a removable version that could be used on multiple vehicles. A little expensive tho.
