I was looking at this as a way to help work on my times and get an idea of the gains im getting with mods instead of going to the dyno and paying hundreds of dollars each time. Does anyone own one or have an experience with it? Thanks guys.

 

I recommend the SeatOPants meter, its free :headbang:

 

i just got mine and i love it. cost $26 on ebay for the older model new in the box. im not sure on how accurate it is but im sure it would help give you an idea. i say go for it.

 

I have i the RR but i have been too busy watching the boost gauge. I havent really even broke out the manual and calibrated it yet but its plugged in. I barely even have time to drive the car.
