I've been running the new TBR slip on system with a Weller Racing ECU tune, and it kicks ass. The slip-on system was an easy install and gives the YXZ a deep tough sound. Without the tune I felt more power and really noticed how much faster I was hitting the rev limiter. Then I had Jason Weller do a tune / flash the ECU and this added power everywhere. I've put a couple hundred miles on it since I had the flash done and the YXZ runs perfectly. I'm very happy with this upgrade and would definitely recommend this setup to others.
