I had 3.73 FRPP gears installed by a shop recommended by some people @ napa and o-reiley's (didn't know where to go so I thought asking them was a start). Then I came home and added the custom tune programmed for me when I ordered the SCT II online. The car feels awesome!!! it pulls hard and feels great 
I do have one concern...I was reading some posts earlier and I came across "gear whine" concerns. I hit up the search button to find out more but I've still got a question for those who might know. I have no idea what oil was added when they installed my gears, they didn't really say anything and I didn't think about it really. There is a SLIGHT, and I mean slight whine. It's barely noticeable, especially at lower speeds. It's more of a whispering sound really, gets louder at speeds of 70 or so. I know FRPP's aren't supposed to have a whine, but should I really be concerned? is a little bit of a whine OK? oh and I have about 70 miles on the gears so far, haven't been pushing it much.
And one more thing, there is a rattling sound coming from underneath my car. I had it checked out a year ago after my Xpipe was added and it was the 02 sensors apparently. Any way to fix those up so that they don't get loose?
