Great power, good if you keep the DPF on, but overpriced.

 

I Have to agree with the slow download with the PPE, not bad on the older models but the 08 can be a pain if your pulling the tuner out all the time. If just changin tunes works very fast a least for me. The price too is up there. The pros that never got mentioned are the trans relearn feature and real time data, nice for diagnostics. I didnt find a problem with the tow tunes seemed to work fine, and there power on the high tunes is almost unbeatable. Except for EFI live that is.. 60000 Mi on mine .. just my 2c
