I currently have a 2010 GSR with bone stock motor. I am considering bolt ons and a pro-tune in the near future

I have searched for a comprehensive thread covering this info, but none turned up that covered this specifically. I apologize if this is a repost.

 

Mods: In signature
I got my intake and exhaust on within 3000 miles.
Yes I am tuned for them
Total 21000 miles as of yesteday
Car has been through 5 track days and countless 50-100 mile spirited drives.
No problems yet, the transfer case did go out about 5000 ago but the dealership said it was a defect.
