I recently down loaded REV. It is the shizit. It is the most awesome tool for monitoring your car and it does it wirelessly. It knows the VIN and will track 1/4 times and speeds with a complete log. The boost gauge is right on the button. It has 32 different gauges.

I am buying a slingbox this weekend and will be able to watch anything that's on TV right on my iphone with no additional charges.

 

Just looked at rev, Looks cool.
