which power kit do I get

[davemon]

I'm curious then how Fabspeed posts these dynos? Do they just run until they find anomolies?

The previous owner had this work done to mine, so I thought it was a nice bonus when I picked the car up. Also this car moved better than the other I testdrove, but that one could have had something else going on, or it could have just been the 200lb salesman in the passenger seat

But still I just don't know how in good conscience this company can make these claims if by everyone else's accounts, they flatly adversely affect HP.
