I also upgraded the transmission fluid to Adrenaline Speed Shift per Rods recommendation.

I still haven't put a lot of 'fun' miles on it yet, but I was able to chirp second gear on stock engine power yesterday LOL

Everything is great so far, I'll report back when I get some more miles on it. Coming up on 50K and I also need to do a trans flush, so I'm not trying to get too crazy yet.
